Tommy earned $1070 less than Jay each month. Both of them spent $1710 each month and saved the rest of their salaries. After a few months, Tommy saved $2380 and Jay saved $7490.
- How much did Tommy earn each month?
- Tommy wanted to go on a trip that would cost him $5100. How many months did he have to save?
(a)
Amount that Jay saved more than Tommy each month = $1070
Total amount that Jay saved more than Tommy
= 7490 - 2380
= $5110
Number of months that each of them earned
= 5110 ÷ 730
= 7
Amount that Tommy's savings each month
= $2380 ÷ 7
= $340
Amount that Tommy earned each month
= 1710 + 340
= $2050
(b)
Remaining amount that Jay had to save
= 5100 - 2380
= $2720
Number of more months that Jay needed to save
= 2720 ÷ 340
= 8
Answer(s): (a) $2050 ; (b) 8
