Pierre earns $60 per day. He receives and extra $30 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 31 days?
(a)
Amount that Pierre earns after working for 4 days
= 60 x 4 + 30
= 240 + 30
= $270
(b)
Number of sets of 4 days in 31 days
= 31 ÷ 4
= 7 r 3
Amount that Pierre earns for working 7 sets of 4 days
= 7 x 270
= $1890
Amount that Pierre earns after working 3 days
= 3 x 60
= $180
Total amount that Pierre earns after working for 31 days
= 1890 + 180
= $2070
Answer(s): (a) $270; (b) $2070
