Peter spent $42 on a blouse. He spent
111 of his remaining money on a vest. If he still had
59 of his money left, how much did he have at first?
| Blouse |
Remaining amount |

Vest |
Left |
| $42 |
1 |
10 |
| 4x2 |
5x2 |
| 7 u |
1 u |
10 u |
The amount that Peter had left is the same. Make the numerators the same. LCM of 5 and 10 is 10.
5x29x2 of his money =
1011 of his remaining money
1018 of his money =
1011 of his remaining money
Amount that Peter spent on the blouse = 7 u
7 u = 42
1 u = 42 ÷ 7 = 6
Amount that Peter had at first
= 18 u
= 18 x 6
= $108
Answer(s): $108
