Domain and range problem help please

The domain is the number of copies made (N)

The range is the is the total cost of the books (C)

The domain we know that they made 200 copies, so the domain would be 0-200.

The range would be:

C=10(200)+700

C=200+700

C=900

Range would be 700-900

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
