Ethan spent $90 on a dress. He spent
111 of his remaining money on a shirt. If he still had
58 of his money left, how much did he have at first?

5x2 |
| 5 u |
1 u |
10 u |
The amount that Ethan had left is the same. Make the numerators the same. LCM of 5 and 10 is 10.
5x28x2 of his money =
1011 of his remaining money
1016 of his money =
1011 of his remaining money
Amount that Ethan spent on the dress = 5 u
5 u = 90
1 u = 90 ÷ 5 = 18
Amount that Ethan had at first
= 16 u
= 16 x 18
= $288
Answer(s): $288
