Luis saved $90 per month for a scooter. At the end of 7 months, he found that the amount of savings he had was only
25 the price of the scooter.
- How much was the scooter?
- How much more must Luis save in order to buy the scooter?
(a)
Amount that Luis saved for 7 months
= 7 x 90
= $630
Amount of savings = 2 u
Price of the scooter = 5 u
2 u = 630
1 u = 630 ÷ 2 = 315
Price of the scooter
= 5 u
= 5 x 315
= $1575
(b)
Amount that Luis must save more to buy the scooter
= 1575 - 630
= $945
Answer(s): (a) $1575; (b) $945
