s = 2.5w + 10

Step-by-step explanation:

You have $10.00. Each week you save $2.50. The number of weeks you save w increases your savings s. Write an equation relating your savings s to the number of weeks you save w.

Your total savings (s) =

How many weeks you have been saving * how much you earn every week + the amount of money you already have.

So, the final equation should be:

w * 2.5 + 10 = s

Simplify.

s = 2.5w + 10
