Andy earned $1110 less than Jay each month. Both of them spent $1660 each month and saved the rest of their salaries. After a few months, Andy saved $2160 and Jay saved $4440.
- How much did Andy earn each month?
- Andy wanted to go on a trip that would cost him $4320. How many months did he have to save?
(a)
Amount that Jay saved more than Andy each month = $1110
Total amount that Jay saved more than Andy
= 4440 - 2160
= $2280
Number of months that each of them earned
= 2280 ÷ 570
= 4
Amount that Andy's savings each month
= $2160 ÷ 4
= $540
Amount that Andy earned each month
= 1660 + 540
= $2200
(b)
Remaining amount that Jay had to save
= 4320 - 2160
= $2160
Number of more months that Jay needed to save
= 2160 ÷ 540
= 4
Answer(s): (a) $2200 ; (b) 4
