Math problem about hours worked and wages earned.In a regular week, there are 5 working days and for each day, the working hours are 8.A man gets $...

Given:

Working days per week = 5 days

Regular working hours per day = 40 hours

Normal wage rate = $2.40 per hour

Over-time wage rate = $3.2 per hour

Total weeks worked = 4 weeks

Total earning for 4 weeks = $432

The total normal working hours for 4 week:

= 4 x (Working hours per week) = 4 x 40 = 160 hours

Wages for normal work for 160 hours:

= 160 x (normal wages per hour) = 160 x 2.4 = 384 $

Wages for over-time:

= (Total earnings) - (Wages for normal work) = 432 - 384 = 48 $

Over-time hours worked:

(Wages for over-time)/(Over-time wage rate)

= 48/3.2 = 15 hours.

Total hours worked:

= (Normal working hours for 4 week) - (Over-time hours worked)

= 160 + 15 = 175 hours

Answer:

He works for 175 hours.
