The calories in a cup of low fat milk is 102 calories and the calories in a cup of milk in skim 86 calories .
<h3>What are the two simultaneous equations that can be sued to represent this question?</h3>
2/3l + 1/2s = 111
4l + 3s = 666 equation 1
l + s = 188 equation 2
Where:
l = calories in the low fat milk
s = calories in the skim milk
<h3>What is the calories in the skim milk?</h3>
Multiply equation 2 by 4
4l + 4s = 752 equation 3
Subtract equation 1 from 3
s = 86
<h3>What is the calories in the low fat milk?</h3>
Substitute for s in equation 2
l + 86 = 188
l = 188 - 86
l = 102
