Question

A sweater is on sale for 20% off the regular price. The sale price is $60. What is the regular price of the sweater?

Answer 1

100-20=80%
percent means parst out of 100
80%=80/100=8/10=4/5

60=80% of original
60=4/5 of original
times both sides by 5/4
300/4=original
75=original

regular price is $75

Answer 2

20% of 300 is 60.. But I might be wrong
