b. How much fat would you expect a 330-calorie hamburger to have?
c.

Answer 3

A. Use a graphing calculator
B. I believe it is equal to or less than 15 grams of fat because for every time the calories went up by 15, the grams of fat goes up about 1. I think I used restaurants D and E to figure that out.
C. I think 36g of fat for a 660-calorie burger is not reasonable, because the grams of fat is too high to match the graph.
