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 = $60
Cost of the doll = 1 u
(a)
Cost of the doll
= 60 ÷ 2
= $30
(b)
Cost of the toy car more than the doll
= 2 u - 1 u
= 1 u
= 1 x 30
= $30
(c)
Cost of 1 toy car and 1 doll
= 2 u + 1 u
= 3 u
= 3 x 30
= $90
(d)
Cost of 5 toy cars and 6 dolls
= 5 x 2 u + 6 x 1 u
= 10 u + 6 u
= 16 u
= 16 x 30
= $480
Answer(s): (a) $30; (b) $30; (c) $90; (d) $480
