item in store is advertised 1/5 off the original price, if the sale price is $140 what is the original price

Question

steps on how to figure it out

Answer 1

1 - 1/5 = 4/5

 

If we let x = the original price:

4/5x = 140

We then multiply both sides by 5/4:

x = 140 * 5/4

Factor out a 5 in the 140:

x = (35*4) * 5/4

The fours in the numerator and denominator cancel each other out:

x = 35 * 5

x = 175

 

So the original price is $175
