Answer 1

150 - 7.50x = 112.50

x = 5

Explanation:

Spent in x days: 7.50x

Initial - spent = remaining

150 - 7.50x = 112.50

If x is also to be found:

150-112.5 = 7.5x

37.5 = 7.5x

x = 37.5/7.5

x = 5

Answer 2

5 Days

Explanation:

Step 1: Make an expression

150 - 7.50x = 112.50

Step 2: Solve the expression for x

150 - 7.50x = 112.50

150 - 7.50x - 150 = 112.50 - 150

-7.50x / -7.5 = -37.5 / -7.5

x = 5

Answer: 5 Days
