Question

An infant drinks 2 ounces of formula every 4 hours. The doctor wants the infant to increase his intake to 4 ounces every 4 hours. What percent increase is this?

Answer 1

The percent increase = 100%

Explanation:

• Given that an infant drinks 2 ounces of formula every 4 hours. Thus, the initial value = 2 ounces per 4 hours

• The doctor wants the infant to increase his intake to 4 ounces every 4 hours. Thus, the final value = 4 ounces per 4 hours

We need to determine the percentage increase.

Using the formula

% increase = 100% × (final - initial)/ initial

= 100% × (4 - 2)/2

= 100% × 2/2

= 100% × 1

= 100%

Thus, the percent increase = 100%
