Answer 1

Aidan saved 115.67 over five weeks.

Explanation:

After x weeks:

The amount of money saved by Aidan is given by:

`y(x) = 17.63x + 27.52`

How much aidan saved over five weeks?

This is y when x = 5. So

`y(x) = 17.63x + 27.52`

`y(5) = 17.63*5 + 27.52 = 115.67`

Aidan saved 115.67 over five weeks.
