An ice cream maker decided that ice cream with 7% butterfat is the best to sell. How many gallons of ice cream with 5% butterfat should be mixed with ice cream that is 15% butterfat to make 200 gallons of the desired blend?

Respuesta :

Given:

Percentage of butterfat to be used = 7%

Amount of blend to be made = 200 gallons.

Let's determine the number of gallons of ice cream with 5% butterfat that should be mixed with ice cream of 15% butterfat to make the desired amount of blend.

Amount of butterfat that is to be in the mixture:

[tex]\text{ 7\% }\ast200=0.07\ast200=14\text{ gallons}[/tex]

Where:

x = amount of gallons of 5%

y = amount of gallons of 15%

We have:

x + y = 14
