19 of his remaining money on a jacket. If he still had
47 of his money left, how much did he have at first?

5 u |
1 u |
8 u |
The amount that Billy had left is the same. Make the numerators the same. LCM of 4 and 8 is 8.
4x27x2 of his money =
89 of his remaining money
814 of his money =
89 of his remaining money
Amount that Billy spent on the jumpsuit = 5 u
5 u = 75
1 u = 75 ÷ 5 = 15
Amount that Billy had at first
= 14 u
= 14 x 15
= $210
Answer(s): $210
