Question

Alicia's doctor has put her on a diet of 600 calories per meal. This means she can consume no more than 600 calories at any meal. Her options for lunch in the cafeteria are as follows:

Yogurt that has 120 calories per serving
Mini Sandwiches that have 100 calories per serving
Which inequality below can be used to find the possible combinations of servings of yogurt (y) and mini sandwiches (s) she can eat and stay within her goal of no more than 600 calories?

Answer 1

y servings of yogurt will have
\[120y\] calories, and
s servings of sandwiches will have
\[100s\] calories
combined they will have
\[12y+100s\] calories, and this has to be less than 600
