Answer 1

Answer:

The shop can cut the cost of production per sandwich to $3.75.  The revenue function would then be defined as R(x)=9x.

Step-by-step explanation:

We want to make as big profit as possible by making as little sandwiches as possible. This means that we want the profit, which is $revenue- production\: cost$ to be as big as possible.

For the first choice the profit per sandwich is $8.25-4=4.25$ dollars.

For the second choice the profit per sandwich is $9-3.75=5.25$ dollars.

For the third choice the profit per sandwich is $8.5-3.5=5$ dollars.

We see here that for the second choice the profit is greatest, therefore this choice is most suitably correct.
