PSLE Oscar and Lee were paid a total of $2500 for a job they did. Lee was paid $1880 less than Oscar.
- How much was Lee paid for the job?
- Oscar and Lee were paid based on the number of days they worked. Oscar worked 5 times as many days as Lee. Oscar was paid $8 more than Lee per day. How many days did Oscar work?
(a)
Amount that Lee was paid = 1 u
Amount that Oscar was paid = 1 u + 1880
Total amount paid
= 1 u + 1 u + 1880
= 2 u + 1880
2 u + 1880 = 2500
2 u = 2500 - 1880
2 u = 620
1 u = 620 ÷ 2 = 310
Amount that Lee was paid
= 1 u
= $310
(b)
Amount that Oscar was paid
= 1 u + 1880
= 310 + 1880
= $2190
Oscar worked 5 times as many days as Lee.
5 sets of Oscar's salary = $2190
1 set of Oscar's salary
= 2190 ÷ 5
= $438
1 set of Lee's salary = $310
Difference between each set of Oscar's and Lee's salaries
= 438 - 310
= $128
Number of days in 1 set
= 128 ÷ 8
= 16
Number of days that Oscar worked
= 5 x 16
= 80
Answer(s): (a) $310; (b) 80
