Yen paid $54 for one sweater and one shirt. The shirt costs 5 times as much as the sweater.
- How much did the sweater cost?
- How much more did the shirt cost than the sweater?
(a)
Cost of the sweater = 1 u
Cost of the shirt = 5 u
Total cost of the sweater and the shirt
= 1 u + 5 u
= 6 u
6 u = 54
1 u = 54 ÷ 6 = 9
Cost of the sweater = $9
(b)
Cost of the shirt more than the sweater
= 5 u - 1 u
= 4 u
= 4 x 9
= $36
Answer(s): (a) $9; (b) $36
