    Trouble with simple word problem

    Seller is being furnished metal castings from Buyer. The cost of castings is $15,000.
    Seller will "machine" the castings to arrive at a finished part, and Seller's total charge to Buyer for its machining labor is $5000 per casting.
    Buyer wants Seller to machine 10 castings to arrive at a finished part.
    Seller includes the cost of the castings, or $150,000, in its proposal to Buyer, plus $50,000 for its machining labor of $5000x10 castings. Total proposal price is $200,000.
    Buyer is allowed to mess up 15% of the order without penalty; in other words, Buyer can machine and mess up 1.5 parts out of the total 10 castings.
    BUT if Buyer messes up more than 15%, Seller must pay for a portion of the casting, but only to the extent that Seller will still make 15% profit.
    Question:
    What if Seller messes up 16%, or 1.6 parts?
    How much of the casting cost can Seller reimburse Buyer which would still allow Seller to make 15% profit? (15% x $200,000=$30,000 total profit is required.)
    Solve.

    Hello and welcome to MathHelpForum.
    You should understand that this is not a homework service nor a tutorial service.
    So you need to either post some of your own work on a problem or explain what you do not understand about the question.
