(a) Write a linear cost function representing the cost C (x) (in S) to the vendor to produce x products. (b) Write a linear revenue function representing the revenue R (x) (in S) for selling x products. (c) Determine the number of products to be produced and sold for the vendor to break even. (d) If 90 products are sold, will the vendor make money or lose money? Part 1 of 4 (a) The linear cost function representing the cost is C (x)=260 + 0.75x Part 2 of 4 (b) The linear revenue function representing the revenue is R (x)= 4x Part: 2/4 Part 3 of 4
