Reggie and Ryan were paid a total of $2040 for a job they did. Ryan was paid $1320 less than Reggie.

1. How much was Ryan paid for the job?
2. Reggie and Ryan were paid based on the number of days they worked. Reggie worked 4 times as many days as Ryan. Reggie was paid $15 more than Ryan per day. How many days did Reggie work? 

(a)
Amount that Ryan was paid = 1 u
Amount that Reggie was paid = 1 u + 1320

Total amount paid
= 1 u + 1 u + 1320
= 2 u + 1320

2 u + 1320 = 2040
2 u = 2040 - 1320
2 u = 720

1 u = 720 ÷ 2 = 360

Amount that Ryan was paid
= 1 u
= $360

(b)
Amount that Reggie was paid
= 1 u + 1320
= 360 + 1320
= $1680

Reggie worked 4 times as many days as Ryan.

4 sets of Reggie's salary = $1680

1 set of Reggie's salary
= 1680 ÷ 4
= $420

1 set of Ryan's salary = $360

Difference between each set of Reggie's and Ryan's salaries
= 420 - 360
= $60

Number of days in 1 set
= 60 ÷ 15
= 4

Number of days that Reggie worked
= 4 x 4
= 16

Answer(s): (a) $360; (b) 16
