# In a regular week, there are 5 working days and for each day, the working hours are 8.

A man gets $ 2.40 per hour for regular work and $ 3.20 per hours for over-time. If he earns $ 432 in 4 weeks, then how many hours does he work for?

A man gets $ 2.40 per hour for regular work and $ 3.20 per hours for over-time. If he earns $ 432 in 4 weeks, then how many hours does he work for?

Suppose the man works over-time for x hours

Now, working hours in 4 weeks = (5 × 8 × 4) = 160.

160 × 2.40 + x × 3.20 = 432 ⇒ 3.20x = 432 – 384 = 48 ⇒ x = 15.

Hence, total hours of work = (160 + 15) = 175.
