Charlie earns $120 per day. He receives and extra $55 for every 4 days of work.
- How much will he earn altogether after working for 4 days?
- How much will he earn altogether after working for 39 days?
(a)
Amount that Charlie earns after working for 4 days
= 120 x 4 + 55
= 480 + 55
= $535
(b)
Number of sets of 4 days in 39 days
= 39 ÷ 4
= 9 r 3
Amount that Charlie earns for working 9 sets of 4 days
= 9 x 535
= $4815
Amount that Charlie earns after working 3 days
= 3 x 120
= $360
Total amount that Charlie earns after working for 39 days
= 4815 + 360
= $5175
Answer(s): (a) $535; (b) $5175
