17 of his remaining money on a vest. If he still had
38 of his money left, how much did he have at first?

5x2 |
3x2 |
9 u |
1 u |
6 u |
The amount that Bobby had left is the same. Make the numerators the same. LCM of 3 and 6 is 6.
3x28x2 of his money =
67 of his remaining money
616 of his money =
67 of his remaining money
Amount that Bobby spent on the jumpsuit = 9 u
9 u = 180
1 u = 180 ÷ 9 = 20
Amount that Bobby had at first
= 16 u
= 16 x 20
= $320
Answer(s): $320
