Practice makes perfect

To determine the percent change p, we can use the following general formula. p % =Amount of increase or decrease/Original amountFrom the given dollar amounts, we can see that the original amount is greater than the new amount. To find the decrease, we have to subtract the new amount from the original one. 4023.52-982.13= 3041.39 Knowing how much the amount decreased, we can use the formula to calculate the percent decrease.

Percent change=Amount of decrease/Original amount
Percent change=3041.39/4023.52
Percent change=0.755902...
Percent change≈ 0.76
Percent change≈ 76 %

The percent change is approximately 76 %.
