Answer 1

Answer: 69.01%

Explanation:

In 1906 Americans consumed an average of 26.85 gallons of milk per year while by 1998 the average consumption was 8.32 gallons.

To get the percent decrease in consumption of whole milk goes thus:

We first find the amount of decrease in the milk consumed. This will be:

= 26.85 - 8.32

= 18.53

Percentage decrease

= 18.53/26.85 × 100

= 0.6901 × 100

= 69.01%
