PSLE Sean and Harry were paid a total of $3670 for a job they did. Harry was paid $1250 less than Sean.
- How much was Harry paid for the job?
- Sean and Harry were paid based on the number of days they worked. Sean worked 2 times as many days as Harry. Sean was paid $5 more than Harry per day. How many days did Sean work?
(a)
Amount that Harry was paid = 1 u
Amount that Sean was paid = 1 u + 1250
Total amount paid
= 1 u + 1 u + 1250
= 2 u + 1250
2 u + 1250 = 3670
2 u = 3670 - 1250
2 u = 2420
1 u = 2420 ÷ 2 = 1210
Amount that Harry was paid
= 1 u
= $1210
(b)
Amount that Sean was paid
= 1 u + 1250
= 1210 + 1250
= $2460
Sean worked 2 times as many days as Harry.
2 sets of Sean's salary = $2460
1 set of Sean's salary
= 2460 ÷ 2
= $1230
1 set of Harry's salary = $1210
Difference between each set of Sean's and Harry's salaries
= 1230 - 1210
= $20
Number of days in 1 set
= 20 ÷ 5
= 4
Number of days that Sean worked
= 2 x 4
= 8
Answer(s): (a) $1210; (b) 8
