An employee is charged $8.00 each day for health care and is paid $16.00 per hour of work.
For this situation the following equation can be written:
Let X denotes the number of hours the employee works in one week.
And Y denotes the total amount of money the employee gets every week for his work. Then we can write:
Y=16*X-5*8 (5 stands for 5 working days per week).
Y=16*X-40
