- How much will 2 toy cars and 2 dolls cost?
Choose the cheaper item to be 1 u.
The toy car costs 2 times as much as the doll.
The doll is cheaper.
Cost of the toy car = 2 u = $100
Cost of the doll = 1 u
(a)
Cost of the doll
= 100 ÷ 2
= $50
(b)
Cost of the toy car more than the doll
= 2 u - 1 u
= 1 u
= 1 x 50
= $50
(c)
Cost of 1 toy car and 1 doll
= 2 u + 1 u
= 3 u
= 3 x 50
= $150
(d)
Cost of 2 toy cars and 2 dolls
= 2 x 2 u + 2 x 1 u
= 4 u + 2 u
= 6 u
= 6 x 50
= $300
Answer(s): (a) $50; (b) $50; (c) $150; (d) $300
