Answer:
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
