Answer:
175%
Step-by-step explanation:
First calculate the price increase (markup). To do this, subtract $8 from $22. The result is $14. Thus, the store sells $8 basketballs for $22, a markup of $14 per ball.
The desired fraction of increase is 14/8, which, as a decimal, comes to 1.75.
Thus, the markup is 175% (after multiplying 1.75 by 100%)
