a company sells brass and steel machine parts. One shipment contain 3 brass and 10 steel parts and cost 48.00. A second shipment contain 7 brass and 4 steel parts and cost 54.00. Find the cost of each type of machine part. How much would a shipment containing 10 brass and 13 steel machine parts cost?

  • Algebra1 -

    Cost of brass part = x
    Cost of steel part = y

    2x + 10y = 48
    7x + 4y = 54

    solve for x and y

    ( I would multiply the first by 2, and the second by 5, then subtract them)
