Cole earned $1350 less than Jay each month. Both of them spent $1870 each month and saved the rest of their salaries. After a few months, Cole saved $7830 and Jay saved $12150.
- How much did Cole earn each month?
- Cole wanted to go on a trip that would cost him $12180. How many months did he have to save?
(a)
Amount that Jay saved more than Cole each month = $1350
Total amount that Jay saved more than Cole
= 12150 - 7830
= $4320
Number of months that each of them earned
= 4320 ÷ 480
= 9
Amount that Cole's savings each month
= $7830 ÷ 9
= $870
Amount that Cole earned each month
= 1870 + 870
= $2740
(b)
Remaining amount that Jay had to save
= 12180 - 7830
= $4350
Number of more months that Jay needed to save
= 4350 ÷ 870
= 5
Answer(s): (a) $2740 ; (b) 5
