Erin needs $100 to pay a bill. She already has $25.00 in the bank. She earns $15.00
per hour at her job. How many hours does she need to work in order to have the
$100 she needs to pay her bill?
Answer:
5 hours
Step-by-step explanation:
100 - 15 = 75
75 ÷ by 15 = 5
Erin will need to work 5 more hours to pay her bill
Answer:
5 hours
Step-by-step explanation:
Erin needs $100 to pay the bill.
She has $25 in the bank.
First let's find how much money she needs more
[tex]100-25=75[/tex]
She needs $75
They said that,
she earns $15 per hour from her job.
Let the unknown hours be x.
Now let's find the hours she have to work to earn $75
1h = $15
x = $75
Use cross multiplication
[tex]75*1=15x\\\frac{75}{15} =\frac{15x}{15} \\5 h=x[/tex]
She needs to work for 5 hours in order to have the $100

What value of w makes the equation below true 7w - 3w = 2(3w + 11)
Answer:
w = -11
Step-by-step explanation:
[tex]7w-3w=2(3w+11)\\4w=6w+22\\-2w=22\\w=-11[/tex]
Answer:
w = -11
Step-by-step explanation:
7w - 3w = 2(3w + 11)
Combine like terms on the left
4w = 2(3w + 11)
Divide by 2
4/2w = 2/2(3w + 11)
2w =(3w + 11)
Subtract 3w from each side
2w-3w = 3w+11-3w
-w = 11
Multiply by -1
w = -11

What is left if I spend 8/15 of my pocket money in fraction?
Answer:
Step-by-step explanation:
You'd start with p, the whole amount of your pocket money, and then subtract (8/15)p, obtaining (7/15)p. In other words, you'd be left with seven fifteenths of your beginning pocket money.
If I spend 8/15 of my pocket money in fraction, then I have left 7/15 money.
What is subtraction?The mathematical operation is subtraction. It is employed to eliminate words or expression's objects.
Given:
I spend 8/15 of my pocket money in fraction.
Let n be the total pocket money.
Then,
left money = n - 8n/15
Left money = (15n - 8n)/15
Left money = 7n/15
Therefore, 7/15 fraction money is left.

Answer:
y = 3/4x +1/4
Step-by-step explanation:
Counting grid squares between the marked points, we find the point on the right is 6 units up and 8 units right of the one on the left. That means the slope of the line is ...
m = rise/run = 6/8 = 3/4
The y-intercept can be found from the slope and one of the points. The coordinates of the point on the left are (x, y) = (-3, -2), so we have ...
b = y -mx
b = -2 -(3/4)(-3) = -2 +9/4 = 1/4
Then the equation of the line is ...
y = mx +b
y = 3/4x +1/4

Below are three advertisements for the same mini fridge from three different stores. You will need to get a credit card from one of the stores in order to buy the fridge. Complete the calculations to determine what the best deal is for you. Show your work!
Mini-Fridge Cost: $300
New Applicant Discount: 10%
Annual Interest Rate: 14.99%
Minimum Monthly Payment: $23
Mini-Fridge Cost: $285
New Applicant Discount: 5%
Annual Interest Rate: 15.99%
Minimum Monthly Payment: $19
Mini-Fridge Cost: $315
New Applicant Discount: 12%
Annual Interest Rate: 12.99%
Minimum Monthly Payment: $26
Part 1: If you only make the minimum payment each month, how long will it take you to pay off each bill AND what is your total for each credit card?
Part 2: If you pay $70 per month for the first 5 months, what will your remaining balance be for each credit card in the 6th month.
Answer:
a) 13 months, $293.82. b) 16 months, $302.25. c) 12 months, $296.18a) $71.55 cr. b) $70.17 cr. c) $65.13 cr. (Or, all are 0 in the 6th month)Step-by-step explanation:
Part 1The attached spreadsheet shows the remaining balance after each payment for each of the payment scenarios. The negative balance at the end of the payment period represents the credit that the account would have if the last payment is the full minimum payment amount. In real life, the last payment would be reduced by that value.
Card A. The 13th payment will result in a credit. It takes 13 months to pay off the credit card. The total of payments is 13×$23 -5.18 = $293.82.
Card B. The 16th payment will result in a credit. It takes 16 months to pay off the credit card. The total of payments is 16×$19 -1.75 = $302.25.
Card C. The 12th payment will result in a credit. It takes 12 months to pay off the credit card. The total of payments is 12×$26 -15.82 = $296.18.
The best deal is Card A.
__
Part 2All of the cards will be completely paid off in 5 months. The remaining balance in the 6th month is zero. The above "Answer" block shows the credit balance each card will have if payments continue to be made for 5 months.
The best deal is Card A, which will have the lowest total of payments.
_____
How the calculations are done
The balance at each step in the spreadsheet is computed as ...
(previous balance) × (1 + rate/12) - (payment)
For example, the balance after the first payment on card A is ...
$270 × (1 +0.1499/12) -23.00 = $273.37 -23.00 = $250.37
Each calculation is rounded to cents, as it would be on a real credit card.

Answer:
5 students
Step-by-step explanation:
The total no. of students in the class is 25=100%
20% of this 25 students are in a club;
Therefore, 25 = 100%
? = 20%
=(20×25)/100
=5 students.
Answer:
5
Step-by-step explanation:
The total number of students = 25 and 20% out of them are in a club
