Answer:
25% or ¼
Explanation:
We are told that the milk contains 2% (0.02) fat and gross cream contains 18%(0.18) that makes you contain 6%(0.06)
Let x be the volume of the cream in the mixture.
Since 1 cup, then volume of milk in the mixture will be; (1 - x)
Setting up the equation, we have;
0.18x + 0.02(1 - x) = 0.06
0.18x + 0.02 - 0.02x = 0.06
0.16x = 0.06 - 0.02
x = 0.04/0.16
x = 0.25
Converting to percentage gives; 25% or ¼
