Use x as the base variable. All others as x+(extra amount).
This is the function

Then factor 2 out

Divide both side by two and use the quadratic formula to get the following

X=3 And x=-2 and don't forget to Chek them
The school council will have 216 small sandwiches.
Step-by-step explanation:
Sandwiches ordered = 12
Length of one sandwich = 6 feet
1 foot = 12 inch
