He can eat a total of 500 calories.
Each fry has 10 calories.

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 = 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.
