3 brothers, Yoko, Tina and Elyse, paid a total of $42 for a gift. Yoko paid
13 of what the rest paid. Tina paid

Total |
| 1x3 |
3x3 |
4x3 |
| 5x2 |
1x2 |
6x2 |
| 3 u |
7 u |
2 u |
12 u |
Total cost of the gift = 12 u
12 u = 42
1 u = 42 ÷ 12 = 3.50
Amount that Elyse paid
= 12 u - 3 u - 2 u
= 7 u
= 7 x 3.50
= $24.50
Answer: $24.50
