5^10 / 5^8 = 5^2 = 25 so the equation becomes 25 = (1/5) ^ n. This means that n = -2.
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%.
