Rich and Betsy Cuik started a small business. They manufacture a microwavable coffee-to-go cup called Cuik Cuppa Coffee. It contains spring water and ground coffee beans in a tea-bag-like pouch. Each cup costs the company $1.00 to manufacture. The fixed costs for this product line are $1,500. Rich and Betsy have determined the demand function to be q = -1,000p + 8,500, where p is the price for each cup.
Write the expense equation in terms of the demand, q.
Express the expense equation found in part (a) in terms of the price, p.
Answer: E= 1.00q + 1,500

Answer:
v² - 6su²v - 7s²[tex]u^{4}[/tex]
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
= v(v + su²) - 7su²(v + su²) ← distribute both parenthesis
= v² + su²v - 7su²v - 7s²[tex]u^{4}[/tex] ← collect like terms
= v² - 6su²v - 7s²[tex]u^{4}[/tex]
write the equation for the graph

12. The second of three numbers is one less than the first. The third
number is 5 less than twice the second. If the third number exceeds the
first number by 12, find the three
numbers.
Answer:
The three numbers are 19, 18, and 31.
Step-by-step explanation:
The three numbers are x, y, and z.
y=x-1
z=2y-5
z=x+12
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
y=18
z=31
The three numbers are 19, 18 and 31
what is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
let the three numbers be x, y, and z.
So, according to question
The second of three numbers is one less than the first,
y = x-1
The third number is 5 less than twice the second,
z=2y-5
also, If the third number exceeds the first number by
12z=x+12
Now, equating the equations
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
So, y=18 and z=31.

The temperature at 2 am was -12 degrees. At noon the temperature had risen 16 degrees. At 4 pm the temp dropped 8 degrees. What was the temperature at 4 pm
Answer: - 4
because The temperature at 2 am was -12 degrees and At noon the temperature had risen 16 degrees
=> the temperature at noon was -12 + 16 = 4 (degrees)
At 4 pm the temp dropped 8 degrees => the temperature at 4 pm was:
4 - 8 = -4 (degrees)

Kathy deposits $500 into an investment account with an annual rate of 1.5%, compounded annually. The amount in her account can be determined by the formula A = P(1 + R)^t, where P is the amount deposited, R is the annual interest rate, and t is the number of years the money is invested. If she makes no other deposits or withdrawals, how many years, to the nearest tenth, will it take for her money to double in value?

C. the number is 6
Answer:
x = -8
Step-by-step explanation:
let's say the number is equal to x; seven times the number is 7x;
then it says minus the number so 7x-x is equal to -48
7x-x=-48; combine the x's
6x = -48; now divide by 6
x = -8

Answer:
71 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180 degrees. If we take that total 180 and subtract 38, we get 142 degrees. If we divide that by two, because the angles are the same, we get 71 degrees. Therefore x=71
A metallurgist wants to make 130 grams of an alloy that is to be 20% copper. She has samples that are 14% copper and 22% copper. How many grams of the sample that contains 14% should she use?
Answer:
She should use 32.5 g of the sample that contains 14%
Step-by-step explanation:
Here, we want to know the number of grams of the sample that contains 14% copper that should be used
let the number of grams that contains 14% copper to be used be x
Then the number of grams of 22% will be 130-x
Thus, mathematically;
0.14(x) + 0.22(130-x) = 0.2(130)
0.14x + 28.6 - 0.22x = 26
0.22x - 0.14x = 28.6 - 26
0.08x = 2.6
x = 26/0.08
x = 32.5
