The sale price of an item is $180 after a 25% discount is applied. What is the original price of the item?
Valentin [98]
So
100%=original
25% discount
100-25=75
it is 180 sale
75%=180
find 100%

a hack is to recognize that 75/3 times 4=100 so
75%=180
divide 3
25%=60
times 4
100%=240


the real way is proportions
75:180 =100:x
75/180=100/x
multiply both sides by 180x
75x=18000
divide 75
x=240



origitnal price=$240
