Shirt |
Total |
1x6 = 6 u |
6x6 = 36 u |
7x6 = 42 u |
5x7 = 35 u |
1x7 = 7 u |
6x7 = 42 u |
6 u |
29 u |
7 u |
42 u |
Total amount that Zoe paid for the skirt, the windbreaker and the shirt = 42 u
42 u = 210
1 u = 210 ÷ 42 = 5
Total cost of the shirt and the skirt
= 6 u + 7 u
= 13 u
= 13 x 5
= $65
Answer(s): $65
