*( / means per)
Okay, so he works 40 hours/ week and works for a year. There are approximately 52 weeks in a year.
First 4 weeks he earns $14/ hour
Rest of the year he earns $18/ hour
First 4 weeks => 40 hours x $14 x 4 weeks = $2240
52 - 4 = 48 weeks after => 40 hours x $18 x 48 weeks = $34560
Total=> 2240 + 34560 = $36,800
The driver earns that total amount in a year.
