Solve the problem.Regrind, Inc. regrinds used typewriter platens. The variable cost per platen is $1.90. The total cost to regrind 90 platens is $500. Find the linear cost function to regrind platens. If reground platens sell for $9.60 each, how many must be reground and sold to break even?
A. C(x) = 1.90x + 329; 29 platens B. C(x) = 1.90x + 329; 43 platens C. C(x) = 1.90x + 500; 65 platens D. C(x) = 1.90x + 500; 44 platens
