Charlie earned $1220 less than Jay each month. Both of them spent $1100 each month and saved the rest of their salaries. After a few months, Charlie saved $3640 and Jay saved $8540.
- How much did Charlie earn each month?
- Charlie wanted to go on a trip that would cost him $7800. How many months did he have to save?
(a)
Amount that Jay saved more than Charlie each month = $1220
Total amount that Jay saved more than Charlie
= 8540 - 3640
= $4900
Number of months that each of them earned
= 4900 ÷ 700
= 7
Amount that Charlie's savings each month
= $3640 ÷ 7
= $520
Amount that Charlie earned each month
= 1100 + 520
= $1620
(b)
Remaining amount that Jay had to save
= 7800 - 3640
= $4160
Number of more months that Jay needed to save
= 4160 ÷ 520
= 8
Answer(s): (a) $1620 ; (b) 8
