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 = $40
Cost of the doll = 1 u
(a)
Cost of the doll
= 40 ÷ 2
= $20
(b)
Cost of the toy car more than the doll
= 2 u - 1 u
= 1 u
= 1 x 20
= $20
(c)
Cost of 1 toy car and 1 doll
= 2 u + 1 u
= 3 u
= 3 x 20
= $60
(d)
Cost of 2 toy cars and 10 dolls
= 2 x 2 u + 10 x 1 u
= 4 u + 10 u
= 14 u
= 14 x 20
= $280
Answer(s): (a) $20; (b) $20; (c) $60; (d) $280
