Respuesta :

Answer:

answer is 1/4 cup

Step-by-step explanation:

Answer:

Amount of cream in cups [tex]=\frac{1}{4}[/tex]

Step-by-step explanation:

Let x be the amount of cream in cups.

Amount of milk = 1 - x cups.

The milk contains 2% fat and cream contains 18% fat.

The mixture contains 6% fat, so we have

         [tex]1 \times \frac{6}{100}=x \times \frac{18}{100}+(1-x) \times \frac{2}{100}\\\\6=18x+2-2x\\\\16x=4\\\\x=\frac{1}{4}[/tex]

Amount of cream in cups [tex]=\frac{1}{4}[/tex]
