If you work for an hourly wage, your gross pay is a function of the number of hours that you work. Your hourly wage is $8.50 per hour. Let n represent the number of hours worked and f(n) represent the gross pay. Write an equation for f(n) in terms of n.
a. f(n) =8.5n
b. f(n)= n/8.5
c. f(n)= n+8.5
d. f(n)= 8.5/n
