Kathy paid $40 for one shirt and one sweater. The sweater costs 4 times as much as the shirt.
- How much did the shirt cost?
- How much more did the sweater cost than the shirt?
(a)
Cost of the shirt = 1 u
Cost of the sweater = 4 u
Total cost of the shirt and the sweater
= 1 u + 4 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Cost of the shirt = $8
(b)
Cost of the sweater more than the shirt
= 4 u - 1 u
= 3 u
= 3 x 8
= $24
Answer(s): (a) $8; (b) $24
