Question 358139
A popular brand of running shoes cost $68 for each pair. If the store sells the shoes for $119, what is the percent of increase in the price? 
.
The "increase" is 119-68 = $51
.
So, the "percent of increase" is
51/68 * 100
.75 * 100
75%
.
That is, there was a 75% increase in price (from cost).
