Answer:
Point (2, 20) does not lie on the given curve.
Step-by-step explanation:
Let us see explanation:

Answer:
M = 3000n(20 - n) dollars.
Step-by-step explanation:
Given that, each machine sets up in one day.
Therefore, n number of machines will take n days to set up.
Now, there are 20 days' time to deliver all the t-shirts.
And the machines are turned on after all the n machines are set up.
So, all the n machines will work for (20 - n) days and producing each machine 200 shirts in one day, then one machine will produce 200(20 - n) number of t-shirts and n machines will produce 200n(20 - n) number of t-shirts in the remaining (20 - n) days.
Now, the selling price for each t-shirt is $15.
Therefore, the total amount of money M she will receive will be, M = 15 × 200n(20 - n) = 3000n(20 - n) dollars. (Answer)
