Final answer:
The price of the fries and the drink is $2.50, the price of the cheeseburger is $7.50, and the total price of the meal is $12.50.
Step-by-step explanation:
Let's say the price of the fries is x. According to the given information, the cheeseburger is three times the price of the fries and the drink, and the fries and the drink have the same price.
So, the price of the cheeseburger would be 3x, and the price of the fries and the drink would be x.
Given that the entire meal costs $12.50, we can set up the following equation: x + x + 3x = 12.50.
Simplifying the equation yields 5x = 12.50. Dividing both sides by 5, we find that x = 2.50.
Therefore, the price of the fries and the drink is $2.50, the price of the cheeseburger is $7.50, and the total price of the meal is $12.50.
