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