How would you work this problem? Thanks!
Josie paid $72.00 for a baseball glove. Price reflected 10% discount off regular price. What was regular price?

assume x is the undiscounted price
100% of x  10% of x = 72
1.00x  0.10x = 72
x (1.000.10) = 72
x (0.90) = 72
x = 72 / 0.90
x = 80
Regular price is $80.00
