Answer:

Final price = 9.6*(105/100) = 9.6*1.05 = 10.08 $

Step-by-step explanation:

The original price of the album is 12 to find out the price after the discount is applied we need to compute 100% - 20% = 80% of the original price. So we can use the following expression:

Price after discount = original price * (80/100)

Price after discount = 12 * (80/100)

Price after discount = 12 * 0.8 = 9.6 $

Now we have to include the sale tax of 5%, since it's a tax we need to add it to the original value so 100% + 5% = 105% of the sale's price:

Final price = Price after discount * (105/100)

Final price = 9.6*(105/100) = 9.6*1.05 = 10.08 $

Answer:

Total price of the album including tax is $10.08

Step-by-step explanation:

Sales price without discount and tax = $12

% discount = 20%

Sales price with discount = 12 - (20/100 × 12) = 12 - 2.4 = $9.6

% sales tax = 5%

Tax = 5/100 × 9.6 = $0.48

Total price of the album including tax = $9.6 + $0.48 = $10.08

Answer:

The method we will use to solve applications with linear inequalities is very much like the one we used when we solved applications with equations. We will read the problem and make sure all the words are understood. Next, we will identify what we are looking for and assign a variable to represent it. We will restate the problem in one sentence to make it easy to translate into an inequality. Then, we will solve the inequality.

The equation y 16t 2 18t 405 describes the height in feet of a ball thrown downward at 18 feet per second from a height of 405 f
kumpel [21]

Answer:

Ball hits the ground after 4.5 sec

Step-by-step explanation:

Let a -1, so that the leading coefficient is positive

So our quadratic is

-1 \times (16t^2 +18t -405)

The key coefficients of two binomial variables can be 1 and 16, or 2 and 8, or 4 and 4, for the leading coefficient of 16.

Yet they can't actually be 4 and 4 because the linear (x) term coefficient has to be a multiple of 4, which it isn't and leading coefficients 1 and 16 on the binomial factors is not likely.

So, 2 and 8 taken as the leading coefficients of  two binomial factors.

For constant  405, possible factorizations are (81\times 5, 27 \times 15, 9 \times 45).

(16t^2 +18t -405) = (8t + 45) (2t - 9)

Taking first factor, thus we find  negative value for given time t. But  second time equivalent to zero gives the value of 4.5 for t

Thus ball hits the ground after 4.5 sec
