a pair of sneakers is on sale for $51 this is 75% of the original price, what is the original price of the shoes?
sertanlavr [38]
Ok so first u have to devide the 51 into 4. So 51 divided by 4 is 12.75. Then it is 75% of it so 75% is 3/4 so you will have to multiply 12.75 by 3. That would equal 38.25. YOUR ANSWER IS 38.25
