Blake needs a minimum of $145. He has saved $35 and plans to save $5.50/wk.

About how many weeks will it take for Blake to save enough money?

A.

at least 20 wk

B.

at most 20 wk

C.

at least 33 wk

D.

at most 33 wk

The equation we'll be using to solve this is:

5.50x + 35 = y, where x is the number of weeks, and y is how much money he has

We're trying to find out how many weeks it takes Blake to raise $145, so we can plug that in for y and then solve for x

5.50x + 35 = 145

Subtract 35 from each side

5.50x=110

Divide each side by 5.5

x=20

The answer is A. at least 20 weeks
