Question

Last year, the price of a 45-ounce box of detergent was $3.75. This year, the price of a 45-ounce box of detergent is $4.50. What was the percent of increase in the detergent?

Answer 1

First, we need to find out how much the price increased by.

$4.50 - $3.75 = $0.75

Now we have to figure out what percent $0.75 is of $3.75. To do this, we divide $0.75 by $3.75.

The answer is 0.2. Now, we convert this into a percent by moving the decimal to the right by to spaces: 0.2 = 20%

The percent of increase is 20%.

Answer 2

My bad I had the calculations wrong.  I have deleted my answer because of it.
