Question

Dexter wrote the equation below to find the number of hours he would need to work at $10 an hour to save $300.

10x + 160 =300

According to this equation, how much money did Dexter already have saved before he started working?

Answer 1

We already know that he is trying to save 10 dollars a week and his goal is 300 so we know that has to be in the equation. 160 is the only one not mentioned in the back round information so we can say that the 160 dollars is the amount of money he already had saved before he started working

Answer 2

10x+160=300
-160 -160
10x=140
10 10
X=14
