Bobby saved $84 per month for a motorbike. At the end of 9 months, he found that the amount of savings he had was only
27 the price of the motorbike.
- How much was the motorbike?
- How much more must Bobby save in order to buy the motorbike?
(a)
Amount that Bobby saved for 9 months
= 9 x 84
= $756
Amount of savings = 2 u
Price of the motorbike = 7 u
2 u = 756
1 u = 756 ÷ 2 = 378
Price of the motorbike
= 7 u
= 7 x 378
= $2646
(b)
Amount that Bobby must save more to buy the motorbike
= 2646 - 756
= $1890
Answer(s): (a) $2646; (b) $1890
