Xylia paid $63 for one blouse and one shirt. The shirt costs 6 times as much as the blouse.
- How much did the blouse cost?
- How much more did the shirt cost than the blouse?
(a)
Cost of the blouse = 1 u
Cost of the shirt = 6 u
Total cost of the blouse and the shirt
= 1 u + 6 u
= 7 u
7 u = 63
1 u = 63 ÷ 7 = 9
Cost of the blouse = $9
(b)
Cost of the shirt more than the blouse
= 6 u - 1 u
= 5 u
= 5 x 9
= $45
Answer(s): (a) $9; (b) $45
