Answer :

Answer:

Part A y = 15(1 + 0.4)^x.

Part B  434 after 10 days.

Step-by-step explanation:

Part A.

21 = 15 ( 1 + r)^1

15 + 15r = 21

15r = 6

r = 6/15 = 0.4

So the equation is

y = 15(1 + 0.4)^x.

Part B.

So after 10 days  x = 10

y = 15(1 + 0.4)^10

y = 434 to the nearest whole number.

Answer:

y = 434 to the nearest whole number.
