Bobby earns $70 per day. He receives and extra $40 for every 5 days of work.
- How much will he earn altogether after working for 5 days?
- How much will he earn altogether after working for 47 days?
(a)
Amount that Bobby earns after working for 5 days
= 70 x 5 + 40
= 350 + 40
= $390
(b)
Number of sets of 5 days in 47 days
= 47 ÷ 5
= 9 r 2
Amount that Bobby earns for working 9 sets of 5 days
= 9 x 390
= $3510
Amount that Bobby earns after working 2 days
= 2 x 70
= $140
Total amount that Bobby earns after working for 47 days
= 3510 + 140
= $3650
Answer(s): (a) $390; (b) $3650
