5. That cool CD you have been waiting to purchase has finally gone on sale over at Wal-Mart for 25% off the original price. You borrow your room-mates employee discount card and head on over to your local Wal-Mart. It turns out the employee discount entitles you to an additional 15% off the sale price of the CD. If the original price was $32.99, what was the total final price you paid for your cool new CD including the 7.5% sales tax

$22.61

Step-by-step explanation: A 25% discount means that instead of paying the full value, you will pay 25% less. So the total price you will pay for a CD of $32.99:

P₁ = 32.99 * (1 - 0.25)

P₁ = 32.99 * (0.75)

P₁ = 24.7425

However, you still have a discount of 15% over the price, so:

P₂ = 24.7425 * (1 - 0.15)

P₂ = 24.7425 * (0.85)

P₂ = 21.03

The sales tax is a value incorporated over the price after all the discounts:

P = 21.03 * (1 + 0.075)

P = 21.03 * (1.075)

P = 22.61

The total final price for the CD is $22.61.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
