Arada [10]

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.

Some please help me I’ll give you brainlist answer
Montano1993 [528]

Answer:

Step-by-step explanation:

The area of the square is 3 units by 3 units. because the area of a square is side length squared.

side length = 3

side length^2 = 3 * 3 = 9

The area of a circle is much harder to reason out. You could start with the area of a square and use the diameter is 3 units. But the corners are rounded and you don't know off hand what the area of one of them is, let alone all 4. You are given a formula for circles area, but you have no real idea what the formula actually means. Does it take the corner area into account? At the beginning levels, we don't know.
