Answer:
(3, 2) is the ordered pair for the given system of equations.
Step-by-step explanation:
Given:
2 x+ y = 8.......................(i)
y = - x + 5........................(ii)
<u>Put y = - x + 5 in equation (i)-</u>
<em>2 x + ( - x+ 5) = 8</em>
<em>2 x - x + 5 = 8</em>
<em>x = 8 - 5</em>
<em>x = 3</em>
<u>Now put x = 3 in equation (ii)-</u>
<em>y = - 3 + 5</em>
<em>y = 2</em>
Hence the (3, 2) is the correct ordered pair.

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)
