Andy spent $10 on a shirt. He spent
15 of his remaining money on a coat. If he still had
25 of his money left, how much did he have at first?

4 |
3x2 |
2x2 |
5 u |
1 u |
4 u |
The amount that Andy had left is the same. Make the numerators the same. LCM of 2 and 4 is 4.
2x25x2 of his money =
45 of his remaining money
410 of his money =
45 of his remaining money
Amount that Andy spent on the shirt = 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Amount that Andy had at first
= 10 u
= 10 x 2
= $20
Answer(s): $20
