Solve the problem.Regrind, Inc. regrinds used typewriter platens. The variable cost per platen is $1.90. The total cost to regrind 100 platens is $300. Find the linear cost function to regrind platens. If reground platens sell for $9.50 each, how many must be reground and sold to break even?
A. C(x) = 1.90x + 110; 10 platens B. C(x) = 1.90x + 110; 15 platens C. C(x) = 1.90x + 300; 40 platens D. C(x) = 1.90x + 300; 27 platens
