Solve.Regrind, Inc. regrinds used typewriter platens. The variable cost per platen is $1.70. The total cost to regrind 60 platens is $400. Find the linear cost function to regrind platens. If reground platens sell for $10.10 each, how many must be reground and sold to break even?
A. C(x) = 1.70x + 400; 48 platens
B. C(x) = 1.70x + 400; 34 platens
C. C(x) = 1.70x + 298; 36 platens
D. C(x) = 1.70x + 298; 26 platens
