Sagar sold a watch at Rs.400 that he had purchased at Rs.500.what is his
percentage loss?
a. 15%
b. 20%
c.25%
d. 30%
Answers
Explanation:
Original price (OP): $500
Selling price (SP): $400
Percentage loss:
= (OP - SP)/OP x 100%
= (500-400) / 400 x 100%
= 100/400 x 100%
= 1/4 x 100%
= 25%
The loss percentage is 20%.
We have the following information available from the question is:
Saggar sold a watch at Rs.400 that he had purchased at Rs.500.
We have to find the Percentage loss.
Now, According to the question:
Cost price of watch is (CP): $500
Selling price of watch is (SP): $400
Loss percentage= Loss/CP x 100.
Loss = C.P. - S.P.
Loss = 500 - 400
Loss = $100
Plug all the values in the formula of loss percentage.
Loss percentage = 100/500 x 100
Loss Percentage is 20%

Dagny Taggart has just purchased a home and taken out a $300,000 mortgage. The mortgage has a 25 year term with monthly payments and has an APR of 6% (monthly compounding). The total amount of interest that Dagny will pay during the first month of her mortgage is closest to:
a.
1923.24
b.
1816.93
c.
1500
d.
1485
Answers
Answer:
c.
1500
Step-by-step explanation:
The computation of the total amount of interest in first month is shown below:
Interest for first month is
= Mortgage amount × interest rate ÷ total number of months in a year
= $300,000 × 6% ÷ 12
= $1,500
Hence, the interest in the first month is $1,500
Therefore the c option is correct
The ratio of the volume of orange juice in Glass A to the volume of orange juice in
Glass B is 5: 3. Half of the orange juice in Glass A is poured into Glass B. What is the
new ratio of the volume of orange juice in Glass A to the volume of orange juice in
Glass B?
Answers
Answer: A:B = 3:13
Step-by-step explanation:
B 5, A 3 (double to get rid of halves)
B 10, A 6, —> B 13 A 3
The question needs you to find the new ratio of the glasses
The new ratio of glass A to glass B = 2.5 : 5.5
Glass A = 5
Glass B = 3
Half of the orange juice in Glass A is poured into Glass B
B = 3 + 1/2 of 5
= 3 + (1/2×5)
= 3 + 5/2
= 6 + 5 / 2
= 11/2
B = 11/2
= 5.5
A = 5 - 1/2 of 5
= 5 - (1/2×5)
= 5 - 5/2
= 10-5/2
= 5/2
= 2.5
The new ratio of glass A to glass B = 2.5 : 5.5

Select the number line that includes the fewest number of T-shirts Carlene can sell and still meet her goal.
Answers
1. $20.50X + $900= $10,740
2. Subtract $900 to both side
3. $20.50X= $9,840

What is the probability that a randomly selected car in the city needs a major repair during its first year of purchase? b. If a car in the city needs a major repair during its first year of purchase, what is the probability that it is a brand A car?
Answers
Answer:
a.) 0.115
b.) 0.087
Step-by-step explanation:
Given,
P(A) = 20% = 0.20
P(B) = 30% = 0.30
P(C) = 50% = 0.50
Let M - major repairing during first year
P(M/A ) = 0.05
P(M/B) = 0.10
P(M/C) = 0.15
a.)
P(M) = P(M∩A) + P(M∩B) + P(M∩C)
= P(M/A).P(A) + P(M/B).P(B) + P(M/C).P(C)
= (0.05)(0.20) + (0.30)(0.10) + (0.15)(0.50)
= 0.01 + 0.03 + 0.075
= 0.115
⇒P(M) = 0.115
b.)
P(A/M) = P(A∩M)/ P(M) = P(M/A).P(A)/P(M)
= (0.05)(0.20) / 0.115
= 0.01 / 0.115 = 0.087
⇒P(A/M) = 0.087

A function assigns the values. The exponential function that goes through (0, 13) and (3, 832) is y=13(4)ˣ.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the exponential eqation is y=abˣ, substitute any one of the point in equation we will get,
13 = ab⁰
13 = a ₓ 1
a = 13
Therefore, the function can be written as y=13bˣ.
Substitute other point in the equation,
832 = 13 (b³)
b³ = 832/13
b³ = 64
b = 4
Hence, the exponential function that goes through (0, 13) and (3, 832) is y=13(4)ˣ.

Step-by-step explanation:
3y/2 - 1 = 8
3y/2 = 8 + 1
3y/2 = 9
3y = 9 × 2
3y = 18
y = 18/3
y = 6
Answer:
y = 6
Step-by-step explanation:
[tex]\frac{3y}{2}[/tex] -1 =8
[tex]\frac{3y}{2}[/tex] -1 + 1 =8 +1
[tex]\frac{3y}{2}[/tex] = 9
[tex]\frac{3y}{2}[/tex] × 2 = 9 × 2
3y = 18
3y/3 = 18/3
y = 6
Double check:
[tex]\frac{3(6)}{2}[/tex] - 1 = 8
[tex]\frac{18}{2}[/tex] -1 =8
9 - 1 = 8

Answers

Step-by-step explanation:
okieee
The total cost is $108.01.
What is a percentage?
A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Mary buys a pair of jeans for $24.99, a skirt for $32.99 and a pair of shoes for $49.99.
She has a coupon for 15% off the most expensive item.
And the most expensive item costs $49.99.
That means, 15% of 49.99
15 x 49.99 = $7.4985
So, the total amount 24.99 + 32.99 + 49.99 - 7.4985
= 100.4715
The tax is 7.5%.
That means,
7.5% of 100.4715
7.5 x 100.4715 / 100 = 7.5353625
Now the total cost = 100.4715 + 7.5353625 = 108.0068625
Therefore, $108.01 is the total cost.

[tex]\color{plum}\tt\bold{(b) \: \$3480 }[/tex]
Steps to derive correct option :Money Maria borrowed = $3000
Percentage of simple interest per annum = 4%
Time she took to repay the money she borrowed = 4 years
We know that :
[tex]\color{hotpink}\tt \: Simple \: interest = \color{plum}\frac{principal \times rate \times time}{100} [/tex]
In this case :
Principal = $3000
Rate = 4%
Time = 4 years
Which means. the simple interest :
[tex] = \tt \frac{3000 \times 4 \times 4}{100} [/tex]
[tex] = \tt \frac{48000}{100} [/tex]
[tex]\color{plum} =\tt\$ 480[/tex]
Thus, the interest she has to pay = $480
We know that :
[tex]\color{hotpink}\tt \: Amount \color{plum}= principal + interest[/tex]
Then, the Amount Maria has to pay :
[tex] =\tt 3000 + 480[/tex]
[tex]\color{plum} =\tt \$3480[/tex]
Thus, the amount Maria has to repay after 4 years = $3480
Therefore, the correct option is (b) $3480
