Gem paid $32 for one cardigan and one hoodie. The hoodie costs 3 times as much as the cardigan.
- How much did the cardigan cost?
- How much more did the hoodie cost than the cardigan?
(a)
Cost of the cardigan = 1 u
Cost of the hoodie = 3 u
Total cost of the cardigan and the hoodie
= 1 u + 3 u
= 4 u
4 u = 32
1 u = 32 ÷ 4 = 8
Cost of the cardigan = $8
(b)
Cost of the hoodie more than the cardigan
= 3 u - 1 u
= 2 u
= 2 x 8
= $16
Answer(s): (a) $8; (b) $16
