Let the caloric content of a cheeseburger be $C$ and that of a small order of French fries be $F$. From the given information, we can set up the following system of equations:1. $2C + F = 850$2. $3C + 2F = 1380$Solving this system of equations, we find that $C = 320$ calories and $F = 210$ calories. Therefore, the correct answer is A) Cheeseburger: 320 calories; French fries: 210 calories.
