Choose the cheaper item to be 1 u.
The toy car costs 7 times as much as the doll.
The doll is cheaper.
Cost of the toy car = 7 u = $70
Cost of the doll = 1 u
(a)
Cost of the doll
= 70 ÷ 7
= $10
(b)
Cost of the toy car more than the doll
= 7 u - 1 u
= 6 u
= 6 x 10
= $60
(c)
Cost of 1 toy car and 1 doll
= 7 u + 1 u
= 8 u
= 8 x 10
= $80
(d)
Cost of 4 toy cars and 5 dolls
= 4 x 7 u + 5 x 1 u
= 28 u + 5 u
= 33 u
= 33 x 10
= $330
Answer(s): (a) $10; (b) $60; (c) $80; (d) $330
