Solve the problem.Regrind, Inc. regrinds used typewriter platens. The cost per platen is $1.10. The cost (fixed cost plus variable cost) to regrind 100 platens is $500. Find the linear cost function to regrind platens. If reground platens sell for $10.70 each, how many must be reground and sold to break even?
A. C(x) = 1.10x + 390 break-even = 41 B. C(x) = 1.10x + 500 break-even = 53 C. C(x) = 1.10x + 390 break-even = 34 D. C(x) = 1.10x + 500 break-even = 43
Provide an appropriate response.The height of an object thrown in the air depends on the time since it has been thrown.
