Question
A meat market has ground beef that is 40% fat and extra lean ground beef that is 15% fat. How many pounds of each(ground beef and extra lean) must be together to get total of 50 pounds of "lean" ground beef that is 25% fat?
Answers
Reiny
amount of the 40% beef --- x
amount to the 15% beef --- 50-x
solve for x
.4x + .15(50-x) = .25(50)
I would multiply each term by 100
40x + 15(50-x) = 25(50)
etc
