 Question 259714: write a system of two equations in two unknowns. Ziggy's famous yougurt blends regular yogurt that is 3% fat with its no fat yogurt to obtain low fat yogurt that is 1% fat. How may pounds of regular yogurt and how many pounds of no fat yogurt should be mixed to obtain 60 pounds of low fat yogurt?Answer by stanbon(57407)   (Show Source): You can put this solution on YOUR website!write a system of two equations in two unknowns. Ziggy's famous yougurt blends regular yogurt that is 3% fat with its no fat yogurt to obtain low fat yogurt that is 1% fat. How may pounds of regular yogurt and how many pounds of no fat yogurt should be mixed to obtain 60 pounds of low fat yogurt? --------------------- Equations: Quantity Eq.: x + y = 60 Fat Eq.....:0.03x+0*y = 0.01(60) ===================================== Multiply thru the "Fat" equation by 100 to get: x + y = 60 3x = 60 =============== x = 20 lbs (amt. of 3% yogurt needed in the mixture) y = 60-20 = 40 lbs (amt. of 0% yogurt needed in the mixture) =============================================================== Cheers, Stan H.
