A pair of jeans is on sale for 25% off its original price the sale price is $27 what was the original price of the jeans

X=the original price of the jeans.

x-25% of x=27

we suggest this equation.

x - (25/100) x=27

x - (x/4) = 27

least common multiple=4

4x-x=108

3x=108

x=108/3

x=36

The original prife of the jeans was $36.

To chek.

25% of $36 = (25/100) $36 = (25*$36) / 100=$9

sale price = original price - discount=$36-$9=$27
