Question

Your school raise 125% of its fundraising goal. The goal raised $6,750. What was the goal?

Answer 1

I take it you mean the original goal.
100/x = 125 / 6750
100% is to x and 125 is 6750
100/x = 125/6750 Cross multiply.
100 * 6750 = 125x Divide by 125
100 * 6750 / 125 = x
x = 5400 was the initial goal.
