Total |
1x5 =
5 u |
8x5 =
40 u |
9x5 =
45 u |
4x9 =
36 u |
1x9 =
9 u |
5x9 =
45 u |
| 5 u |
31 u |
9 u |
45 u |
Total amount that Zoe paid for the vest, the skirt and the windbreaker = 45 u
45 u = 90
1 u = 90 ÷ 45 = 2
Total cost of the windbreaker and the vest
= 5 u + 9 u
= 14 u
= 14 x 2
= $28
Answer(s): $28
