Question 1199097: Sandwich shop has a fixed expense of $2000 ,and the cost of making each sandwich is 1.20 .
If C is used for the monthly cost and n for the number of sandwiches made
What would be the number of sandwiches made if the cost is $3500.
I can do it on the linear but can't do it mathematically.
C= 1.2n+ 2000

You can put this solution on YOUR website!
You have found almost all you need. "Linear"? "Mathematically"?

C is obviously the cost.
1.2n%2B2000=3500
So you know what to solve for.
