1x5 = 5 u |
6x5 = 30 u |
7x5 = 35 u |
4x7 = 28 u |
1x7 = 7 u |
5x7 = 35 u |
5 u |
23 u |
7 u |
35 u |
Total amount that Zoe paid for the jacket, the blazer and the windbreaker = 35 u
35 u = 105
1 u = 105 ÷ 35 = 3
Total cost of the windbreaker and the jacket
= 5 u + 7 u
= 12 u
= 12 x 3
= $36
Answer(s): $36
