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 = $80
Cost of the doll = 1 u
(a)
Cost of the doll
= 80 ÷ 2
= $40
(b)
Cost of the toy car more than the doll
= 2 u - 1 u
= 1 u
= 1 x 40
= $40
(c)
Cost of 1 toy car and 1 doll
= 2 u + 1 u
= 3 u
= 3 x 40
= $120
(d)
Cost of 4 toy cars and 4 dolls
= 4 x 2 u + 4 x 1 u
= 8 u + 4 u
= 12 u
= 12 x 40
= $480
Answer(s): (a) $40; (b) $40; (c) $120; (d) $480
