Hello there! There are 4 DVD's ordered online, and it costs $9.24 per CD. Let's start off by multiplying 4 and 9.24 together. 9.24 * 4 is 36.96. Samuel gets a 25% discount, so he gets 25% off of the original combined price, but he still has to pay the remaining 75%. To find the new price, all we have to do is multiply the original price of $36.96 by 75% (0.75). When that is done, you should get 27.72. Now, there is a sales tax rate of 6.5%. 6.5% in decimal form is 0.065. Let's add 1 to that in order to get 1.065. Multiply that number by 27.72 to get the new price. 27.72 * 1.065 is 29.5218 or 29.52 when rounded to the nearest cent. The total cost of Samuel's order is $29.52.
