Cole spent $21 on a blazer. He spent
111 of his remaining money on a coat. If he still had
59 of his money left, how much did he have at first?

| $21 |
1 |
10 |
| 4x2 |
5x2 |
| 7 u |
1 u |
10 u |
The amount that Cole 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 Cole spent on the blazer = 7 u
7 u = 21
1 u = 21 ÷ 7 = 3
Amount that Cole had at first
= 18 u
= 18 x 3
= $54
Answer(s): $54
