In 1906 Americans consumed an average of 26.85 gallons of whole milk per year. By 1998 the average consumption was 8.32 gallons. What is the percent decrease in consumption of whole milk?

69.01%

Step-by-step 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%

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
