A woman weighing 250 pounds goes on a diet. During the first week, she loses 3% of her body weight. During the second week, she loses 2%. At the end of the second week, how many pounds has she lost?

12.35

Explanation

First, calculate 3% of 250 pounds: \(250 \times 0.03=7.5\) pounds
Calculate how much she weighs at the end of the first week: 250 - 7.5 = 242.5 pounds. Calculate 2% of \(242.5 \div 242.5 \times 0.02=4.85\) pounds
Add the two values together to get the total: 7.5 + 4.85 = 12.35
