Choose the cheaper item to be 1 u.
The toy car costs 8 times as much as the doll.
The doll is cheaper.
Cost of the toy car = 8 u = $160
Cost of the doll = 1 u
(a)
Cost of the doll
= 160 ÷ 8
= $20
(b)
Cost of the toy car more than the doll
= 8 u - 1 u
= 7 u
= 7 x 20
= $140
(c)
Cost of 1 toy car and 1 doll
= 8 u + 1 u
= 9 u
= 9 x 20
= $180
(d)
Cost of 2 toy cars and 5 dolls
= 2 x 8 u + 5 x 1 u
= 16 u + 5 u
= 21 u
= 21 x 20
= $420
Answer(s): (a) $20; (b) $140; (c) $180; (d) $420
