He can eat a total of 500 calories.
Each fry has 10 calories.
N=500%2F10=50
He can have 50 french fries. Not very nutritious though.

After choosing to consume the hamburger and soda, he'll have 40 calories to go [500- (315 + 145)], which means he can eat 40%2F10 = highlight_green%284%29 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.
