The statement indicates that a store has clearance items that have been marked down by 60% and this means that you have to pay 40% of the price as:
100%-60%=40%
Now, the statement says that the are advertising an additional 45% off clearance items which means that you will have a 45% discount on the 40% of the original price. So, you have to calculate 45% of 40 and subtract that from 40 to find the percentage that you will end up paying:
40*45%=18
40-18=22
According to this, the answer is that you end up paying 22% of the original price.
The graph of y = b is a horizontal line passing through the point (0, b) on the y-axis. To graph an equation of this form, such as y = 4, plot the point (0, b) on the y-axis and draw a horizontal line through it (see Example 4). If the equation is not in the form y = b, solve the equation for y. Vertical Lines: x = a.
