PSLE Lee and Bryan were paid a total of $2530 for a job they did. Bryan was paid $1550 less than Lee.
- How much was Bryan paid for the job?
- Lee and Bryan were paid based on the number of days they worked. Lee worked 4 times as many days as Bryan. Lee was paid $5 more than Bryan per day. How many days did Lee work?
(a)
Amount that Bryan was paid = 1 u
Amount that Lee was paid = 1 u + 1550
Total amount paid
= 1 u + 1 u + 1550
= 2 u + 1550
2 u + 1550 = 2530
2 u = 2530 - 1550
2 u = 980
1 u = 980 ÷ 2 = 490
Amount that Bryan was paid
= 1 u
= $490
(b)
Amount that Lee was paid
= 1 u + 1550
= 490 + 1550
= $2040
Lee worked 4 times as many days as Bryan.
4 sets of Lee's salary = $2040
1 set of Lee's salary
= 2040 ÷ 4
= $510
1 set of Bryan's salary = $490
Difference between each set of Lee's and Bryan's salaries
= 510 - 490
= $20
Number of days in 1 set
= 20 ÷ 5
= 4
Number of days that Lee worked
= 4 x 4
= 16
Answer(s): (a) $490; (b) 16
