Answer:
If Shawn downloads a movie at a price of $ 2 each, for five movies he should pay $ 10. A percentage of 25% calculated as a sum is required to pay multiplied by 0.25. If for five downloaded movies there is a discount of 25%, it means that at a price of $ 10 he will have a 25% discount, $ 10x0.25 (25%) and get a discount of $ 2.5. That means he saved $ 2.5 if he bought five movies, and would pay $ 7.5.

Answer:
Sales Tax In Amount =$99
Total amount of purchase = $1899
Step-by-step explanation:
First, let's find sales tax price in amount(dollars)
(Total Amount)*(percentage of tax)/100=Tax in amount
(1800)*(5.5%)/100 = $99
Therefore, the sales tax in amount would equal to $99, which is the same as 5.5%.
Now, let's find the total price of the purchase.
$1800+$99= $1899
So, the total cost of the purchase would equal to $1899.
For this case the total taxes are given by:

Then, we can make the following rule of three:
11595 ---------> 100%
955 ------------> x
From here, we clear the value of x.
We have then:

x = 8.2%
Answer:
The overall tax rate (to the nearest tenth) is:
8.2%
Let p = number of pennies.
Let n = number of nickels.
We are given that n= 2p and the total value is $8.80.
We know that a penny = $0.01 and that a nickel = $0.05.
So $0.01p + $0.05n = $8.80.
Substitute 2p for n:
$0.01p + $0.05*2p = $8.80
$0.01p + $0.10p = $8.80
$0.11p = $8.80
p = 80
So n = 2p = 2*80 = 160
Thus there are 80 pennies ($0.8) and 160 nickels ($8.00). The value of all the coins is $8.80.
