Ian earned $1170 less than Jay each month. Both of them spent $2570 each month and saved the rest of their salaries. After a few months, Ian saved $4950 and Jay saved $10530.
- How much did Ian earn each month?
- Ian wanted to go on a trip that would cost him $6600. How many months did he have to save?
(a)
Amount that Jay saved more than Ian each month = $1170
Total amount that Jay saved more than Ian
= 10530 - 4950
= $5580
Number of months that each of them earned
= 5580 ÷ 620
= 9
Amount that Ian's savings each month
= $4950 ÷ 9
= $550
Amount that Ian earned each month
= 2570 + 550
= $3120
(b)
Remaining amount that Jay had to save
= 6600 - 4950
= $1650
Number of more months that Jay needed to save
= 1650 ÷ 550
= 3
Answer(s): (a) $3120 ; (b) 3
