Question 310431
Robert is on a diet and can have 500 calorie for lunch. A 3- ounce hamburger on whole wheat bread has 315 calories, and a 12-ounces of soda has 145 calories. How many French fries can he eat if there are 10 calories in one French fry?


After choosing to consume the hamburger and soda, he'll have 40 calories to go [500- (315 + 145)], which means he can eat {{{40/10}}} = {{{highlight_green(4)}}} french fries. 


Who eats 4 french fries? Can someone really eat just 4 french fries? He will have to though if he wants to stick to his diet.
