John earns $80 per day. He receives and extra $40 for every 6 days of work.
- How much will he earn altogether after working for 6 days?
- How much will he earn altogether after working for 40 days?
(a)
Amount that John earns after working for 6 days
= 80 x 6 + 40
= 480 + 40
= $520
(b)
Number of sets of 6 days in 40 days
= 40 ÷ 6
= 6 r 4
Amount that John earns for working 6 sets of 6 days
= 6 x 520
= $3120
Amount that John earns after working 4 days
= 4 x 80
= $320
Total amount that John earns after working for 40 days
= 3120 + 320
= $3440
Answer(s): (a) $520; (b) $3440
