Choose the cheaper item to be 1 u.
The toy car costs 5 times as much as the doll.
The doll is cheaper.
Cost of the toy car = 5 u = $50
Cost of the doll = 1 u
(a)
Cost of the doll
= 50 ÷ 5
= $10
(b)
Cost of the toy car more than the doll
= 5 u - 1 u
= 4 u
= 4 x 10
= $40
(c)
Cost of 1 toy car and 1 doll
= 5 u + 1 u
= 6 u
= 6 x 10
= $60
(d)
Cost of 2 toy cars and 9 dolls
= 2 x 5 u + 9 x 1 u
= 10 u + 9 u
= 19 u
= 19 x 10
= $190
Answer(s): (a) $10; (b) $40; (c) $60; (d) $190
