Question

if a slice of chocolate cake contains 500 calories, how many portions would someone have to eat to gain a pound using the classic rule of calorie balance?
check my work
a. 3 slices
b. 5 slices
c 7 slices
d. 9 slices

Explanation:

Step1: Know the calorie - pound relationship

The classic rule of calorie balance is that to gain 1 pound, a person needs to consume an excess of 3500 calories.

Step2: Calculate the number of slices

If each slice of chocolate cake has 500 calories, then the number of slices \(n\) to gain 1 pound (3500 calories) is calculated by the formula \(n=\frac{3500}{500}\).

$$n = \frac{3500}{500}=7$$

Answer:

C. 7 slices
