Answer:

The number of grilled cheese sandwiches sold was 132 and the number of deep fried Twinkies sold was 271

Step-by-step explanation:

Let

x -----> the number of grilled cheese sandwiches

y -----> the number of deep fried Twinkies

we know that

The system of equations that represent this scenario is equal to

x+y=403 ------> equation A

4.85x+2.95y=1,439.65 ------> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (132,271)

see the attached figure

therefore

The number of grilled cheese sandwiches sold was 132 and the number of deep fried Twinkies sold was 271
