Total |
1x8 = 8 u |
8x8 = 64 u |
9x8 = 72 u |
7x9 = 63 u |
1x9 = 9 u |
8x9 = 72 u |
8 u |
55 u |
9 u |
72 u |
Total amount that Zoe paid for the dress, the vest and the blazer = 72 u
72 u = 144
1 u = 144 ÷ 72 = 2
Total cost of the blazer and the dress
= 8 u + 9 u
= 17 u
= 17 x 2
= $34
Answer(s): $34
