Can someone tell me answers and how to do this? 30 points!!! Will give brainliest

a = 350

r= 75%

y = 5744.6

Step-by-step explanation:

This is in the form

y = a ( 1+r) ^t

Where a is the initial value and r is the rate at which it increases or decreases

y = 350 ( 1+.75) ^t

a = 350

r = .75 or 75% increase

Let t = 5

y = 350 ( 1+.75) ^5

y = 350 ( 1.75)^5

   = 5744.58007

To the nearest tenth

y = 5744.6

a = 350

r = 75%

y = 5744.6

Step-by-step explanation:

The value outside the parentheses is the initial value, so it is 350.

The rate is 0.75 growth, or 75% as a percentage.

Plug in 5 as the exponent:

350(1.75)^5 ≈ 5744.6
