Question

Joshua has $34 in his bank account. With his new job, he deposits the same amount each week into the account. After 35 weeks, Joshua has $909. What function can find the amount in Joshua's account after w weeks?

Answer 1

Greetings!

Answer:

f(x) = 34 + 25w

Explanation:

First, we need to find the amount he was paid over the 35 weeks:

909 - 34 = 875

35w = 875

w = 875 / 35 = 25

So every week he is paid $25

The function has to start with 34, as that is the amount already in there, and as w is multiplying by 25, this can be written as 25w

So put these two together:

f(x) = 34 + 25w

Hope this helps!
