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