K = number of carpenters = 10
<span>C = 15,000+50(10)^2 +60x^2 </span>
<span>C = 15,000+5,000+60x^2 </span>
<span>C = 20,000+60x^2 ----- cost function </span>
<span>Marginal cost function = dC/dx = d/dx [60x^2] = 120x </span>
<span>MC = 120x ----- marginal cost function </span>
<span>Average cost function = C(x)/x = 20,000 /x + 60x </span>
<span>AC = 20,000/x + 60x
</span>Marginal cost when x=14 is:
<span>120(14) = 1,680 </span>
<span>Average cost when x=14 is: </span>
<span>20,000/14 + 60(14) = 2268.57
</span>
<span>Marginal cost is less than the average cost, so the average cost is decreasing as the number of electricians increases.</span>
Answer:
100-(8 times y)
Step-by-step explanation:
The high school softball team needs to buy T-shirts for their games. The T-shirts cost $8 a piece and they only have $100 to spend.
8 a peice
This means that the money costs 8$ for each of the players. We don't know how many players there are, so we will just label the amount of players as "y"
And we will multiply 8 times y to get our answer
And then we will subtract THAT answer minus 100 to get our full answer.
Hope this helps!
Have a great day!
The 5 is 50 and the 8 is 8
or 5 tens and 8 ones hope that helped :)

Answer:
Infinite Many Solutions
Step-by-step explanation:
2x - y = 2 (x + 1)
2x - (-2) = 2( x + 1)
2x + 2 = 2(x + 1)
2x + 2 = 2x + 2(1) : Here I used the distributive property
2x + 2 = 2x + 2: There is infinite many solutions because if you graph this on the graph the lines will be not intercect in only one place but in an infinity amount of places because the two equations are the same in terms of Y = mx + b.
