Solve the problem.Regrind, Inc. regrinds used typewriter platens. The variable cost to regrind each platen is $1.30. The total cost to regrind 110 platens is 
Find the linear cost function to regrind platens. If reground platens sell for 
each, how many must be reground and sold to break even?
A. C(x) = 1.30x + 500; 46 platens B. C(x) = 1.30x + 357; 43 platens C. C(x) = 1.30x + 500; 61 platens D. C(x) = 1.30x + 357; 33 platens
