MATH 133-1102A Unit 4 Group Project ABSTRACT Annual profit in thousands of dollars is given by the function, P(x) = 5000 – (1000/(x-1)), where x is the number of items sold in thousands, x > 1. 1. describe the meaning of the number 5000 in the formula 2. describe the meaning of the number 1 in the formula 3. find the profit for 5 different values of x 4. graph the profit function over its given domain; use the 5 values calculated in part 3 to construct the graph and connect these points with a smooth curve in Excel or another graphing utility. Insert the graph in a Word file and attach the graph in a Word file to the class DB thread. . will this profit function have a maximum, if so, what is it? 6. what steps should the company take to prepare for your answer to part 5? 1.

Dedrana McCray #1The 5000 in the problem represents the limiting profit which is the maximum profit value, which can be the initial amount. www. algebra. com #2One is the limit of the annual profit equation where it determines the rise or increase in the annual profit or the lack their of the Elite Marketing Corporation. X=5 P=Profit P (5) =5000-(1000/ (5-1) I subtracted 1 from 5 and that leaves me with 4

P (5) =5000-(1000/ (5-1) P (5) =5000-(1000/(4) Next I begin to divide the 4 into 1000 and that gave me 250 P (5) =5000-(1000/4) P (5) =5000-250 Next step is to subtract 250 from 5000 and I will have my profit P (5) = 5000-250 P (5) =4750 Which means X is greater or higher than 1 because X which is 5 is greater than because X is what the profit will be at the end of the year and 1 is at the beginning of the year which means the company made a $4,750 profit. X>1 #3 Find the profit for 5 different values of x. ( both “x” and the profit, P(x), are listed in “thousands”) x = 3: P(3) = 5000 – [1000/(3 – 1)] = 5000 – (1000/2) = 4,500 = 5: P(5) = 5000 – [1000/(5 – 1)] = 5000 – (1000/4) = 4,750 x = 7: P(7) = 5000 – [1000/(7 – 1)] = 5000 – (1000/6) = 4,833. 33 x = 9: P(9) = 5000 – [1000/(9 – 1)] = 5000 – (1000/8) = 4,875 x = 11: P(11) = 5000 – [1000/(11 – 1)] = 5000 – (1000/10) = 4,900 #4 #5Will this profit function have a maximum, if so, what is it? Yes, there is a maximum profit; the maximum profit possible is 5000. The larger the value of x becomes the smaller the term 1000 / (x – 1) is, and the closer the function values are to 5,000. For very large values of x, the value of the function will be very, very close to 5,000. #6 REFERENCES: www. algebra. com
