Marion paid $25 for one shirt and one blouse. The blouse costs 4 times as much as the shirt.
- How much did the shirt cost?
- How much more did the blouse cost than the shirt?
(a)
Cost of the shirt = 1 u
Cost of the blouse = 4 u
Total cost of the shirt and the blouse
= 1 u + 4 u
= 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Cost of the shirt = $5
(b)
Cost of the blouse more than the shirt
= 4 u - 1 u
= 3 u
= 3 x 5
= $15
Answer(s): (a) $5; (b) $15
