Rael earned $610 less than Jay each month. Both of them spent $1200 each month and saved the rest of their salaries. After a few months, Rael saved $630 and Jay saved $1830.
- How much did Rael earn each month?
- Rael wanted to go on a trip that would cost him $1890. How many months did he have to save?
(a)
Amount that Jay saved more than Rael each month = $610
Total amount that Jay saved more than Rael
= 1830 - 630
= $1200
Number of months that each of them earned
= 1200 ÷ 400
= 3
Amount that Rael's savings each month
= $630 ÷ 3
= $210
Amount that Rael earned each month
= 1200 + 210
= $1410
(b)
Remaining amount that Jay had to save
= 1890 - 630
= $1260
Number of more months that Jay needed to save
= 1260 ÷ 210
= 6
Answer(s): (a) $1410 ; (b) 6
