Your wage is $11.00 per hour plus $0.50 for each unit produced per hour. So, your hourly wage in terms of the number of units produced x is y = 11 + 0.50x. Find the inverse function. What does each variable represent in the inverse function? ?

A.

x = hourly wage; y = numbers of units produced


B. y = 11 + 0.50x

x = hourly wage; y = numbers of units produced

?
