Laura used to weigh 150 pounds. She now weighs 135 pounds. WHat is the percent of decrease?

10%

Step-by-step explanation: First, subtract to find the amount of change: 150-135 = 15. Next, divide the amount of change by the original amount: 15/150 = 0.1. Now, to change the decimal to a percent, multiply the number by 100: 0.1 x 100 = 10. The answer is 10%. So that's the percent of change, a decrease of 10% in body weight.
