There is a shop with old-style cash registers. Rather than scanning items and pulling the price from a database, the price of each item is typed in manually. This method sometimes leads to errors. Given a list of items and their correct prices, compare the prices to those entered when each item was sold. Determine the number of errors in selling prices.

There is no list of items and their correct and incorrect prices, thus actual and accurate answers cannot be determined.

Step-by-step explanation:

N.B: Since no list is given, accurate answers cannot be given.  

The typing of the bar codes or prices manually in order to determine the price, can lead to errors in the selling price. This can be detrimental for business since undercharging or overcharging can occur.

For example, the price of a dress was recorded as $30 while it should have been $39. The price of a t-shirt was correctly recorded as $10. The price of a pair of jeans was recorded as $25 instead of $23. There are 2 errors in the selling prices found in the above example about clothing items.   the dress is undercharged and the pair of jeans is overcharged.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
