A recording company invests $18,972 for the setup cost for producing a master tape of a band and it costs $1.90 to make each copy of the master tape. Each tape is sold for $9.10.Will someone check my equations for number 1 and 2 and help me figure out number 3?
1. Write an equation to express the total cost of producing t tapes as a function of C(t) = cost.
I got: C(t) = 9.10t - 1.90t- 18,972
2. Write a nequation to express the revenue in selling t tapes as a function of R(t) = revenue.
R(t) = 9.10t
3. Find the coordinates of the point of intersection algebraically.
I have no clue
