How many hours would someone who earns $7.75 per hour have to work to earn $224.72

29 hours

Step-by-step explanation:

Let h represent the number of hours worked. Then wages paid for that time are ...

.. 7.75h = 224.72

Dividing by the coefficient of h lets us find its value.

... 224.72/7.75 = h = 28.996

Someone must work 29 hours at that rate to earn $224.72.

Comment on the answer

The given amount would be the gross pay for working that time period. In the real world, gross pay is rarely the same as net pay. Taxes and other deductions take their toll.

a = 11 : 4

b = 38

c = 1 for every 6
