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
For this problem the work would look like this:
Multiply -2 to both sides to isolate w.
Notice that the sign flips! This is because anytime a negative numbers transfers to the other side of the inequality the inequality flips directions.
Now this should be the solution once solving.
The attached picture below shows the graph.
Hope this helps!
