Question

Hello it’s a 4 part question I just need help however I can only post one picture at a time

Answer 1

Answer:

Part a:

0% 3000

5% 3646.51

10% 5247.02

20% 6220.8

Explanation:

Part a:

We need to evaluate the function in the r values given:

If the rate is 0% then r = 0

$S=3000(1+0)^4=3000$

If the rate is 5%, then r = 0.05

$S=3,000(1+0.05)^4\approx3646.51$

If the rate is 10%, then r = 0.1

$S=3,000(1+0.1)^4=4392.3$

If the rate is 15%, then r = 0.15

$S=3,000(1+0.15)^4=5247.02$

If the rate is 20%, then r = 0.2

$S=3,000(1+0.2)^4=6220.8$
