this above is part b. i need with filling in the blank. will give 15 points for . it's for plato. and i'm add an attachment for part a and the work i have for part a.

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: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

the answer is y = 11.54

hope this : )
