Wyatt bought a pair of shoes for $72. the next week he noticed that the price for the same pair of shoes was now $87. find the percent of change.

(after price-initial price\initial price)100=percent of change
the initial price = 72
(a week later)after price = 87

87-72=15
15/72=.20833333333
.20833333333*100= 20.833333333
the percent of change of initial price of $72 and the after price of $87= 20.833333333= 2.08%

What are the following algebraic equations. you need to post those if you want the answer
