3 cousins, Mary, Risa and Lynn, paid a total of $132 for a souvenir. Mary paid

Total |
| 1x6 |
4x6 |
5x6 |
| 5x5 |
1x5 |
6x5 |
| 6 u |
19 u |
5 u |
30 u |
Total cost of the souvenir = 30 u
30 u = 132
1 u = 132 ÷ 30 = 4.40
Amount that Lynn paid
= 30 u - 6 u - 5 u
= 19 u
= 19 x 4.40
= $83.60
Answer: $83.60
