PSLE Eric and Peter were paid a total of $1570 for a job they did. Eric was paid $890 more than Peter.
- How much was Peter paid for the job?
- Eric and Peter were paid based on the number of days they worked. Eric worked 2 times as many days as Peter. Peter was paid $25 less than Eric per day. How many days did Eric work?
(a)
Amount that Peter was paid = 1 u
Amount that Eric was paid = 1 u + 890
Total amount paid
= 1 u + 1 u + 890
= 2 u + 890
2 u + 890 = 1570
2 u = 1570 - 890
2 u = 680
1 u = 680 ÷ 2 = 340
Amount that Peter was paid
= 1 u
= $340
(b)
Amount that Eric was paid
= 1 u + 890
= 340 + 890
= $1230
Eric worked 2 times as many days as Peter.
2 sets of Eric's salary = $1230
1 set of Eric's salary
= 1230 ÷ 2
= $615
1 set of Peter's salary = $340
Difference between each set of Eric's and Peter's salaries
= 615 - 340
= $275
Number of days in 1 set
= 275 ÷ 25
= 11
Number of days that Eric worked
= 2 x 11
= 22
Answer(s): (a) $340; (b) 22
