Question

   NEED HELP IN WRITING ANEQUATION TO EXPRESS THE REVENUE IN SELLING (t) TAPES AS afunction of R (t) = revenue. It should be noted that revenueis not the same thing as a profit. Revenue is the totalamount of money collected at the time of sale. Where asprofit is the amount of revenue minus the cost of producing anitem.

Using this word problem: A recordingcompany invest $18,972 for the set-up cost for producing a mastertape of a band and it cost $1.90 to make each copy of the mastertape. Each tape (t) is sold for $9.10.

Explanation / Answer

If we are ignoring only the set-up cost, thenR(t)=(9.10*t)-(1.90*t)=7.20*t. If we are ignoring only the cost of each master tape, thenR(t)=(9.10*t)-18972. If we take into account all costs, thenR(t)=(7.20*t)-18972.
However, I think it's the first equation, if your definitionis correct.
