It costs a coat manufacturer $8750 to make 125 coats and it costs $6500 to make 80 coats.  Each coat is sold for $300.    a. How much is the marginal cost?  Round to two decimal places if rounding is necessary.          b. What is the slope of the Profit function, P(x)?  Round to two decimal

Can you help with parts d, e, and f please? The Admission director for a college far from mart and town believes that an inverse relationship exists between a private college's average discount rate(determined by the average amount of scholarships students receive) and the annual yield (the percentage of admitted students who actually attend). The Director's independent variable is a private college's discount rate measured as a percentage, and the dependent variable is the college's annual yield measured as a percentage. The following results were obtained for a sample of 30 private colleges: x- Discount rate(percentage) - range: 35 to 72 percent y- Annual Yield(percentage) - range: 12 o 81 percent Σxi = 1612 Σyi = 898Σxiyi = 44,377Σxi2 = 89,790Σyi2 = 35,704a.

2. Express the slope of the line passing through each pair of points using an integer or reduced fraction, or state that the slope is undefined. Tell if the line through the points rises or falls (from left to right), or is horizontal or vertical. Show your work clearly. a. (2, 4) and (3,-2) b. (-7,-2) and (-7,2) Function P() 8.7z+06 modela er efter 1990 and P(c) gives slope is: the line: slope is: the line:

la. Make a scatter plot of the table provided in the image. B. Write a linear/exponential equation that models this table provided in the image. C. Explain what the slope/multiplier means in the context of the problem. D. Use your model to predict when there will be 100 new cases I have already made a scatter plot so I mainly need help with questions B, C, and D. Thank you for your help!
