Assume that you are considering enhancing a machine by adding a special feature to it. The percentage of time (the original run time before the feature is added) that the machine can be run using this new feature is denote as p%, and, during this portion of time, the machine with this new feature runs f% faster than the old one without it. Required:
a. Determine the overall speedup for each of the following:

i. f = 100, p = 100
ii. f = 100, p = 50
iii. f = 400, p = 50
iv. f = 400, p = 20

b. Draw a graph that plots together each of the two speedup functions for f = 100 and f = 400 in terms of p (y-axis being the speedup and x-axis being p).

7.23 main lab 7 - online shopping cart background this main lab extends the earlier prep lab "online shopping cart part 1". (you should save this as a separate project from the earlier prep lab). you will create an on-line shopping cart like you might use for your on-line purchases. the goal is to become comfortable with setting up classes and using objects. requirements this lab can be done individually or as pair programming. expanded itemtopurchase class (15 points) extend the itemtopurchase class as follows. we will not do unit testing in this lab so we will not be giving you the names of the member functions. create good ones on your own. create a parameterized constructor to assign item name, item description, item price, and item quantity (default values of "none" for name and description, and 0 for price and quantity). additional public member functions set an item description get an item description print the cost of an item - outputs the item name followed by the quantity, price, and subtotal (see example) print the description of an item - outputs the item name and description (see example) additional private data members a string for the description of the item. example output of the function which prints the cost of an item: bottled water 10 @ $1.50 = $15.00 example output of the function which prints the item description:
