Web Mercantile sells many household products through an online catalog. The company needs substantial warehouse space for storing its goods. Plans now are being made for leasing warehouse storage space over the next 5 months. Just how much space will be required in each of these months is known. However since these space requirements are quite different, it may be most economical to lease only the amount needed to each month on a month by month basis. On the other hand the additional cost for leasing space for additional months is much less than for the first month, so it may be less expensive to lease the maximum amount needed for the entire 5 months. Another option is the intermediate approach of changing the total amount of space leased(by adding a new lease and/or having an old lease expire) at least once but not every month. The space requirement and the leasing costs for the various leasing periods are as follows: Read More »

In the Standard Ethernet with the transmission rate of 10 Mbps, we assume that the length of the medium is 2500 m and the size of the frame is 512 bits. The propagation speed of a signal in a cable is normally 2*10^8 m/s. Find the propagation delay. 2. Find the Transmission delay. 3. Find …

John decides to take out a multi-year fixed-rate mortgage of $30,000 to purchase a new car. The interest rate is 3.5% and the monthly payment is $545.75. Write a function, total, to calculate the total amount that he will have to pay over the life of the mortgage. You can ignore the overpayment that occurs in the last month. To calculate each month’s remaining principal: remaining principal of this month = remaining principal of last month * (1 + rate/12) – monthly payment. (You should get an answer of $33290.75.)
