For groups of 80 or more people, a charter bus company determines the rate per person according to the formula:
Rate=8-0.05(n-80),n(greater than or equal to)80
where the rate is given in dollars and 'n' is the number of people.
Now, Express the revenue 'R' for the bus company as a function of 'n'.

Your equation already expresses the revenue R as a function of n
Did you want to express n as a function of R ?
If so, expand it first, then solve for n
R = 8 - .05n + 4
R = 12 - .05n , this is the simplest R expressed as a function of n
.5n = 12 - R
n = (12 - R)/.05
