The profit made from selling $x$ units of a coffee maker per week in a certain market is given by \[ P=-0.1 x^{2}+22 x-400 \] Part: 0 / 4 Part 1 of 4 (a) Find the profit if the company sells 80 coffee makers in this market. The profit from selling 80 coffee makers is $\$ \square$.

Step 1 ：The profit made from selling $x$ units of a coffee maker per week in a certain market is given by \(P=-0.1 x^{2}+22 x-400\).

Step 2 ：To find the profit from selling 80 coffee makers, we need to substitute $x=80$ into the profit function.

Step 3 ：After substituting $x=80$ into the profit function, we get \(P=-0.1 (80)^{2}+22 (80)-400\).

Step 4 ：Calculating the above expression, we find that \(P=720.0\).

Step 5 ：Final Answer: The profit from selling 80 coffee makers is \(\boxed{720}\) dollars.
