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
well the problem does say express the revenue for the bus company as a function of n.
maybe this will help:
here are the answer choices:
4.none of these
thanx so much
You'd have saved yourself and Reiny a lot of time if you'd posted the answer choices in your original message. You also may have gotten a more explicit answer if you'd posted your thoughts on this answer.
well i didn't want to post the answers because someone could easily choose an answer choice. i just wanted to compare reiny's answer to the answer i'd already gotten. i wanted to double check from a credible source.
