Joelle paid $14 for one blouse and one jacket. The jacket costs 6 times as much as the blouse.
- How much did the blouse cost?
- How much more did the jacket cost than the blouse?
(a)
Cost of the blouse = 1 u
Cost of the jacket = 6 u
Total cost of the blouse and the jacket
= 1 u + 6 u
= 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Cost of the blouse = $2
(b)
Cost of the jacket more than the blouse
= 6 u - 1 u
= 5 u
= 5 x 2
= $10
Answer(s): (a) $2; (b) $10
