Alexander wants to build an indoor playing field. The playing field needs to be twice as long as it is wide. Sport Turf costs $4 per square foot. The school has $50,000 to spend on sport turf. What is the largest area that the school can afford to cover in turf?

C. 15%

Step-by-step explanation: Firstly, you need to find the increase.

The increase is the new number - the original number.

In this case, that would be

2,760 - 2,400 = 360

Your increase is 360.

To find the percent increase, you divide your increase by the original number and multiply it by 100:

increase ÷ original number × 100

Plug in your numbers:

360 ÷ 2,400 × 100 = 15%

Your percent of increase is 15%.
