Question

John saved $33. which was 30% of
the money he eamed. How much did
he earn in total?

Answer 1

I would work it out in ratio form
33 = 30

11 = 10 (easiest way is to X by 10)
22= 20
33= 30 (what you have)
44= 40
55= 50
66= 60
77= 70
88= 80
99= 90
110=100 (what your trying to find)

Answer 2

money earned = 110

Explanation:

Money earned * percent saved = money saved

money earned * 30% = 33

Change to decimal form

money earned * .30 = 33

Divide each side by .3

money earned = 33/.3

money earned = 110
