How many ounces of cereal should be added to 125 oz of a 45% mixture of cereal and meat in order to produce a pet food mixture that is 30% cereal?
How many ounces of cereal should be added to 125 oz of a 45% mixture of cereal and meat in order to produce a pet food mixture that is 30% cereal?
How many ounces of cereal should be added to 125 oz of a 45% mixture of cereal and meat in order to produce a pet food mixture that is 30% cereal?
125oz of a mixture with 45% cereal contains:125 x 45%= 56.25oz of cereal
Now imagine that 56.25 oz of cereal were to create a mixture with 30% cereal.
56.25/30% = 187.5 oz
So the new mixture weighs 187.5oz
In this new mixture,the weight of cereal remains unchanged (56.25oz),the only thing that's increased is the meat.
So,187.5-125 = 62.5 oz
That's how much meat has to be added.
