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.

Find the value of the missing variables.
dsp73

Answer:

x^{\circ}=35^{\circ}\\ \\y^{\circ}=55^{\circ}

Step-by-step explanation:

The measure of arc which the right triange cuts from the circle is 70^{\circ}, this means the central angle has the same measure.

Angle with measure x^{\circ} is inscribed angle subtended on the given arc. Its measure is half the measure of the central angle, hence

x^{\circ}=\dfrac{1}{2}\cdot 70^{\circ}=35^{\circ}

Angles with measures x^{\circ} and y^{\circ} are complementary angles (add up to 90°), so

y^{\circ}=90^{\circ}-35^{\circ}=55^{\circ}
