Question

Anna weighs 180 lb. She goes on a diet and loses 15% of her body weight.

How much weight, in ounces, did she lose?

Hint: 1 lb = 16 oz

A: 234 oz
B: 342 oz
C: 343 oz
D: 432 oz

Answer 1

First, we need to find out how much weight Anna lost. To do that, we need to calculate 15% of her body weight:

15% of 180 lb = 0.15 x 180 lb = 27 lb

So Anna lost 27 lb.

To convert pounds to ounces, we know that 1 lb = 16 oz, so we can multiply the weight loss in pounds by 16:

27 lb x 16 oz/lb = 432 oz

Therefore, Anna lost 432 ounces of weight.

The answer is D: 432 oz.
