Cathy paid $49 for one shirt and one jacket. The jacket costs 6 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 = 6 u
Total cost of the shirt and the jacket
= 1 u + 6 u
= 7 u
7 u = 49
1 u = 49 ÷ 7 = 7
Cost of the shirt = $7
(b)
Cost of the jacket more than the shirt
= 6 u - 1 u
= 5 u
= 5 x 7
= $35
Answer(s): (a) $7; (b) $35
