Elijah earned $960 less than Jay each month. Both of them spent $2920 each month and saved the rest of their salaries. After a few months, Elijah saved $3220 and Jay saved $6720.
- How much did Elijah earn each month?
- Elijah wanted to go on a trip that would cost him $7820. How many months did he have to save?
(a)
Amount that Jay saved more than Elijah each month = $960
Total amount that Jay saved more than Elijah
= 6720 - 3220
= $3500
Number of months that each of them earned
= 3500 ÷ 500
= 7
Amount that Elijah's savings each month
= $3220 ÷ 7
= $460
Amount that Elijah earned each month
= 2920 + 460
= $3380
(b)
Remaining amount that Jay had to save
= 7820 - 3220
= $4600
Number of more months that Jay needed to save
= 4600 ÷ 460
= 10
Answer(s): (a) $3380 ; (b) 10
