Final answer:
To find the number of chicken sandwiches sold, we can set up an equation using the total number of sandwiches and the fact that there are 100 more hamburgers than chicken sandwiches.
Step-by-step explanation:
The subject of this question is Mathematics, as it involves solving a mathematical problem related to the sales of hamburgers and chicken sandwiches.
To find the number of chicken sandwiches sold, we can let the number of hamburgers sold be x. Then, the number of chicken sandwiches sold would be x-100, as it is 100 less than the number of hamburgers sold. We know that the total number of sandwiches sold is 500, so we can write the equation: x + (x-100) = 500
Simplifying the equation, we get 2x - 100 = 500. Adding 100 to both sides, we have 2x = 600. Dividing both sides by 2, we find x = 300. Therefore, the number of chicken sandwiches sold is 300 - 100 = 200, and the number of hamburgers sold is 300.
