Hazel paid $28 for one cardigan and one skirt. The skirt costs 6 times as much as the cardigan.
- How much did the cardigan cost?
- How much more did the skirt cost than the cardigan?
(a)
Cost of the cardigan = 1 u
Cost of the skirt = 6 u
Total cost of the cardigan and the skirt
= 1 u + 6 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Cost of the cardigan = $4
(b)
Cost of the skirt more than the cardigan
= 6 u - 1 u
= 5 u
= 5 x 4
= $20
Answer(s): (a) $4; (b) $20
