2. Buying Computer Hardware

3.   A state agency added office space for new employees. To connect the employees to its network, the agency purchased 25 desktop computer systems at $1,689; 25 network cards at $75; network cabling for $625; two other network devices at $96.88 and a network printer for $5,598  The cost of installing each computer, connecting it to the network hardware and cabling was $11,890. What was the total cost of the hardware installed? Example 1

4.   25 x $1,689 = $42,225 (Cost of Desktop Computers)  25 x $75 = $1,875 (Cost of Network Cards)  2 x $96.88 = $193.76 (Cost of Network Devices) Add costs of all hardware and installation. $42,225+ $1,875 + $193.76 +$625+$5,598+$11,980 =$62,406.76 Total Cost of Hardware Solution

5. Leasing Computer Hardware

6.   Thornton College decides to create a new computer laboratory of 35 networked desktop computers. One company offers to lease the desktops to the college for $38.89 per month each for three years. What would be the total cost of the lease? Example 2

7.   3 x12 = 36 (Number of months lease will last)  36 x #38.89 = $1,400.04 (Cost of leasing computer for 3 years)  35 x $1,400.04 =$49,001.40 (Total lease cost of all computers for 3 years) Solution

8. Cost of Buying Software

9.   Brandon Glass Corporation is considering their desktop operating system software from Lenox version 3.5 to Lenox version 4.0 for their 43 computer systems. The per-copy cost of the upgrade is 97.89.  A 50—workstation upgrade license costs $3,800. How much would Brandon save by buying a 50- workstation upgrade license instead of separate copies of the upgrade? Example 1

10.   43 x $97.89 = $4,209.27 (cost of upgrading each workstation  $4,209.27 - $3,800 =$409.27 (savings using 50 workstation license) Solution

11. Developing Software

12.   A new program contains 3,360 lines of code. Three programmers were paid $47 an hour to work on the program and averaged lines of finished code in an 8- hour day. How long did the project take? What was the programming cost of the project? Example 1

13.   3 x 28 = 84 (lines of finished code per day)  3,360 / 84 = 40 (number of days the project took)  3 x 8 = 24 (hours programmers worked in a day)  24 x 40 =960 (total hours needed to complete the project)  960 x $47 = $45, 120 (total cost of programming of the project) Solution
