Question 142937
Robert is on a diet and can have 500 calories for lunch. A 3-ounce hamburger on whole wheat bread has 315 calories, and 12 fluid ounces of soda has 145 calories. How many French fries can he eat if there are 10 calories in one French fry?
--------------
EQUATION:
Let x be the number of fries he can eat.
EQUATION:
x = [500-315-145]/10
x = [40/10] = 4
