Question

Consider a situation where you are buying videos online. The video seller charges $21.50 as the price per video and $6.75 as the handling cost for up to three videos. For every video purchased in addition to three videos, there is a handling charge of $1.50. In addition, there is a 9 percent tax on the cost of the videos but not on the handlingCharges. Assuming that numVideos represents the number of videos you are purchasing, which of the following is the correct algorithm for calculating the total cost of your purchase?
A) Total charge for videos = 21.50 * numVideos
Tax on the videos = numVideos * .9
If (numVideos <= 3) then handlingCharges = 6.75
Else handlingCharges = 1.50 * numVideos
Total cost of order = total charge for videos + tax + handlingCharges
B) Total charge for videos = 21.50 * numVideos
Tax on the videos = total charge for videos * .9
If (numVideos = 3) then handlingCharges = 6.75
Else handlingCharges = 1.50 * numVideos
Total cost of order = total charge for videos + tax + handlingCharges
C) Total charge for videos = 21.50 * numVideos
Tax on the videos = numVideos * .09
If (numVideos < 3) then handlingCharges = 6.75
Else handlingCharges = 6.75 + 1.50 * (numVideos - 3)
Total cost of order = total charge for videos + tax + handlingCharges
D) Total charge for videos = 21.50 * numVideos
Tax on the videos = total charge for videos * .09
If (numVideos <= 3) then handlingCharges = 6.75
Else handlingCharges = 6.75 + 1.50 * (numVideos - 3)
Total cost of order = total charge for videos + tax + handlingCharges

Quizplus · Accepted Answer

The correct algorithm calculates the total charge for videos, applies a 9% tax on the video cost, and correctly calculates the handling charges based on the number of videos purchased. For up to three videos, the handling charge is $6.75, and for more than three, it adds $1.50 for each additional video beyond the third.
