Abi paid $30 for one blouse and one skirt. The skirt costs 4 times as much as the blouse.
- How much did the blouse cost?
- How much more did the skirt cost than the blouse?
(a)
Cost of the blouse = 1 u
Cost of the skirt = 4 u
Total cost of the blouse and the skirt
= 1 u + 4 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Cost of the blouse = $6
(b)
Cost of the skirt more than the blouse
= 4 u - 1 u
= 3 u
= 3 x 6
= $18
Answer(s): (a) $6; (b) $18
