Justin saved $72 per month for a scooter. At the end of 10 months, he found that the amount of savings he had was only
23 the price of the scooter.
- How much was the scooter?
- How much more must Justin save in order to buy the scooter?
(a)
Amount that Justin saved for 10 months
= 10 x 72
= $720
Amount of savings = 2 u
Price of the scooter = 3 u
2 u = 720
1 u = 720 ÷ 2 = 360
Price of the scooter
= 3 u
= 3 x 360
= $1080
(b)
Amount that Justin must save more to buy the scooter
= 1080 - 720
= $360
Answer(s): (a) $1080; (b) $360
