An aerospace company is developing a new fuel additive forcommercial airliners.The additive is composed of threeingredients:X,Y, andZ. For peak perfor-mance, the total amount ofadditive must be at least 6 mL/L of fuel. For safetyreasons, thesum of the highly flammableYandZingredients must not exceed2.5mL/L. In addition, for the additive to work, the amount ofZmust begreaterthan or equal to twice the amount ofY, and the amountofXmust be greaterthan or equal to three quarters of the amountofY. If the cost per mL for theingredientsX,YandZis 20 cents, 3cents, and 5 cents, respectively, use MSexcel to determine theminimum cost of the additive mixture for each liter of fuel.
