Question

The table shows the annual increase in cost in t years for certain grocery items. Based on the formula A = C(1 + r)t, which equation could you use to determine the cost in t years for a gallon of milk?

Answer 1

Given A=C(1+r)t
to get the formula for cost we make C the subject as follows
divide both sides by (1+r)t, this will give us:
A/(1+r)t=C
hence the cost function will be:
C=A(1+r)^(-t)

Answer 2

Answer:

The answers A = 4.25(1.10)^t
