Samuel's order will ultimately cost $39.84.
One DVD Samuel purchased cost $9.96.
He purchased four DVDs in total.
as a result, his total outlay will be 4 * 9.96 = $39.84.
The 7.75% sales tax that must be paid is disclosed to us.
Adding 7.75% to $39.84 yields
39.84 x 7.75/(100) (100)
= $3.0876
Consequently, the total amount of tax due is $3.0876.
Using 25% of 39.84 to calculate a 25% discount,
39.84 x 25/100
= 996/100
=$9.96
Consequently, the total discount on the total of $39.84 will be $9.96.
as a result, the updated purchase price will be,
39.84-9.96
=$29.88
adding the tax to the updated price,
9.96+29.88
= $39.84
Consequently, Samuel's order will ultimately cost $39.84.
<h3>How are percentages calculated?</h3>
One must compute percentage in order to determine the proportion of a whole that is stated in terms of 100. A percentage can be determined using one of two methods:
using the unitary method.
by changing the fraction's denominator to 100.
It should be noted that the second method of percentage computation is not used when the denominator is not a factor of 100. In these circumstances, we make use of the unitary approach.
