Oscar earns $70 per day. He receives and extra $25 for every 3 days of work.
- How much will he earn altogether after working for 3 days?
- How much will he earn altogether after working for 23 days?
(a)
Amount that Oscar earns after working for 3 days
= 70 x 3 + 25
= 210 + 25
= $235
(b)
Number of sets of 3 days in 23 days
= 23 ÷ 3
= 7 r 2
Amount that Oscar earns for working 7 sets of 3 days
= 7 x 235
= $1645
Amount that Oscar earns after working 2 days
= 2 x 70
= $140
Total amount that Oscar earns after working for 23 days
= 1645 + 140
= $1785
Answer(s): (a) $235; (b) $1785
