y = -24x + 379

y represents money left
x represents weeks

We are finding the amount of weeks for the account to have $67 left.

Substitute y = 67

67 = -24x + 379
-312 = -24x

Divide both sides by -24 to get x by itself,

x = 13

Therefore the answer is 13 weeks!

Hope this helped!
13 weeks is the answer
