A manufacturer buys large quantities of certain fuel pumps. He finds that his cost depends on the number of cases, q, bought at
ruslelena [56]

Answer:

The correct option is <u>c) $17.50/case</u>.

Step-by-step explanation:

Note: The data in the question are merged. The data are therefore sorted and the whole question is represented before answering the question. Please, see the attached pdf file for the sorted data and the represented question.

The explanation of the answer is now given as follows:

Marginal cost refers to the cost incurred in order to produce one more unit of a product.

Therefore, marginal cost is the change in the total cost that is caused by a one-unit increase in the quantity of a commodity that is produced.

From the table in the question, the marginal cost at q = 108 can be calculated as follows:

Change in total quantity at 180 cases = 108 - Number of cases immediately before 108 = 180 - 104 = 4

Change in total cost at 180 cases = Total cost at 108 cases - Total cost immediately before 108 cases = 1990 - 1920 = 70

Marginal cost at 108 cases = Change in total cost at 180 cases / Change in total quantity at 180 cases = 70 / 4 = 17.50 per case

Therefore, the correct option is <u>c) $17.50/case</u>.

I need the answers for this slide! :( Seriously it's like nothing we learned in class. I don't understand this
gtnhenbr [62]

Hopefully I can explain this well enough..

If you've ever heard of slope, it is the same as constant of proportionality. If you haven't, it's pretty simple to find on a graph. Look where the line perfectly hits the graph numbers by at least two times. So, on the graph, you can see that it goes through (1, 4) and (2, 8). You can find the slope two ways from this point, but I'm not really sure how to explain it just from typing, so I'll explain one the way it's written.

The formula for finding slope is y2-y1/x2-x1. Plugging in the numbers in the equation, it should look like 8-4/2-1, which simplifies to 4. This is the complicated way, so I'm sorry, but if you want to do the graph way, the way it's written is rise/run.

Equations are y=mx+b. m stands for slope and b is the y-intercept. We covered the slope (4), so we just need the intercept. The intercept is just asking where the line goes through y. We can see that it started at 0, so the equation is simply y=4x.

Now onto the second question. I'm a little confused if the number of baskets is x, or if the cost is x... I'm just going to go on and guess that the Number of Baskets is x.

Finding the constant of proportionality is so much easier on this because you can do 12/3 which gets you 4. All of the others have this too, so you know it's 4. In the end, the equation is, once again, y=4x.  

So, in the end, these should and hopefully be the correct answers:

3.

Constant of Proportionality: 4

Equation: y=4x

4.

Constant of Proportionality: 4

Equation: y=4x

3.9999893 round to 4 places
Blizzard [7]

Answer:

its 4

Step-by-step explanation:

Because since the next number is 8 and its above 5 then a number above 9 is something you cannot put in so you just round the whole number since the rest of the numbers are also 9.

Please hurryyyyyyuu
allochka39001 [22]

Answer:

2·(2a^3 - a^2+6)

Step-by-step explanation:

(((0-(5•(a^3)))-(7•(a^2)))+3)+(((9•(a^3))+5a^2)+9)

(((0-(5•(a^3)))-(7•(a^2)))+3)+((3^2a^3+5a^2)+9)

(((0-(5•(a^3)))-7a^2)+3)+(9a^3+5a^2+9)

(((0 -  5a^3) -  7a^2) +  3) +  (9a^3 + 5a^2 + 9)

  Pull out like factors :

4a3 - 2a2 + 12  =   2 • (2a3 - a2 + 6)

Hope it helps!
