Pierre earned $1050 less than Jay each month. Both of them spent $2280 each month and saved the rest of their salaries. After a few months, Pierre saved $2700 and Jay saved $9450.
- How much did Pierre earn each month?
- Pierre wanted to go on a trip that would cost him $5400. How many months did he have to save?
(a)
Amount that Jay saved more than Pierre each month = $1050
Total amount that Jay saved more than Pierre
= 9450 - 2700
= $6750
Number of months that each of them earned
= 6750 ÷ 750
= 9
Amount that Pierre's savings each month
= $2700 ÷ 9
= $300
Amount that Pierre earned each month
= 2280 + 300
= $2580
(b)
Remaining amount that Jay had to save
= 5400 - 2700
= $2700
Number of more months that Jay needed to save
= 2700 ÷ 300
= 9
Answer(s): (a) $2580 ; (b) 9
