Question

Izzy goes on a "cleanse"(ing) diet, consuming only water with honey, which contains 1500 Calories per day. If Izzy's body uses 1500 Calories per day to survive, and one pound of fat contains 3000 Calories, how many pounds of fat will she lose in 8 days

Answer 1

The correct answer is 4 pounds of fat.

Explanation:

Izzy is consuming only water with honey, which contains 1500 Calories per day.

Izzy's body uses 1500 Calories per day to survive.

Amount of calories consumed by Izzy in 8 days = 1500 × 8 = 12000.

Izzy loses all the 12000 calories in 8 days time.

Now, 1 pound of fat contains 3000 Calories

By unitary method, 1 calorie =
`(1)/(3000)` pounds of fat

∴ 12000 calories would constitute
`(12000)/(3000)` = 4 pounds of fat.

Thus Izzy will lose 4 pounds of fat in 8 days.
