Ivan saved $90 per month for a motorbike. At the end of 8 months, he found that the amount of savings he had was only
49 the price of the motorbike.
- How much was the motorbike?
- How much more must Ivan save in order to buy the motorbike?
(a)
Amount that Ivan saved for 8 months
= 8 x 90
= $720
Amount of savings = 4 u
Price of the motorbike = 9 u
4 u = 720
1 u = 720 ÷ 4 = 180
Price of the motorbike
= 9 u
= 9 x 180
= $1620
(b)
Amount that Ivan must save more to buy the motorbike
= 1620 - 720
= $900
Answer(s): (a) $1620; (b) $900
