Cole earned $830 less than Jay each month. Both of them spent $1750 each month and saved the rest of their salaries. After a few months, Cole saved $770 and Jay saved $5810.
- How much did Cole earn each month?
- Cole wanted to go on a trip that would cost him $1540. How many months did he have to save?
(a)
Amount that Jay saved more than Cole each month = $830
Total amount that Jay saved more than Cole
= 5810 - 770
= $5040
Number of months that each of them earned
= 5040 ÷ 720
= 7
Amount that Cole's savings each month
= $770 ÷ 7
= $110
Amount that Cole earned each month
= 1750 + 110
= $1860
(b)
Remaining amount that Jay had to save
= 1540 - 770
= $770
Number of more months that Jay needed to save
= 770 ÷ 110
= 7
Answer(s): (a) $1860 ; (b) 7
