George earned $890 less than Jay each month. Both of them spent $1610 each month and saved the rest of their salaries. After a few months, George saved $1890 and Jay saved $8010.
- How much did George earn each month?
- George wanted to go on a trip that would cost him $2520. How many months did he have to save?
(a)
Amount that Jay saved more than George each month = $890
Total amount that Jay saved more than George
= 8010 - 1890
= $6120
Number of months that each of them earned
= 6120 ÷ 680
= 9
Amount that George's savings each month
= $1890 ÷ 9
= $210
Amount that George earned each month
= 1610 + 210
= $1820
(b)
Remaining amount that Jay had to save
= 2520 - 1890
= $630
Number of more months that Jay needed to save
= 630 ÷ 210
= 3
Answer(s): (a) $1820 ; (b) 3
