Michael is buying a new pair of headphones from an electronics store. The headphones cost $15.50, but Michael has a coupon that will reduce the cost by $4.00. He must pay 6% sales tax on the discounted price of the headphones. How much will Michael pay in total for the headphones, including tax?

Answers

Answer: Michael pays $12.19 for the headphones including the tax.

Step-by-step explanation:

The initial price of the headphones was $15.50

When Michael uses his coupon, the price is decreased by $4, then the new price will be:

$15.50 - $4 = $11.50

Now Michael must pay 6% for taxes (on the discounted price), then he must pay:

$11.50 + (6%/100%)*$11.50

$11.50 + 0.06*$11.50

$11.50*1.06 = $12.19

Then Michael pays $12.19 for the headphones including tax.

Answer:

  x = 23

Step-by-step explanation:

Eliminate parentheses, separate the variables and the constants, divide by the coefficient of the variable.

  7(x +4) = 9(x -2) . . . . . given

  7x +28 = 9x -18 . . . . . eliminate parentheses using the distributive property

  28 = 2x -18 . . . . . . . . . subtract 7x*

  46 = 2x . . . . . . . . . . . . add 18

  23 = x . . . . . . . . . . . . . divide by 2

The solution is x = 23.

Check

7(23+4) = 9(23-2)   ⇒   7·27 = 9·21 . . . true (=189)

__

* We choose to subtract 7x instead of 9x so that the resulting x-term has a positive coefficient.

_____

Additional comments

The properties of equality tell you that you can do anything you like to an equation, as long as you do the same thing to both sides of the equation. So, when we say "subtract 7x", we mean that value is subtracted from both sides of the equation. Subtracting a value, or adding its opposite, is a way to remove a term from a place in the equation where you don't want it.

Here, the smaller x-coefficient is on the left, so we choose that term to subtract. That leaves the remaining x-term on the right (with a positive coefficient). We don't want any constants there, so we add the opposite of that constant. (The opposite of -18 is 18, so that is what we add--to both sides.)

__

Sometimes you will be told differently. You will be told to "put that over there and change its sign" or "cross-multiply". These instructions are based on appearance. The fundamental, always-applicable rule is "do the same thing to both sides of the equation." With practice and understanding, you can begin to think in terms of these shortcut suggestions.

Answers

Answer:

y = 6.50x + 6 or 71 = 6.50x + 6

10 people are the max you can invite

Step-by-step explanation:

We have the simple equation

y = 6.50x + 6

6.50x because it it per person

6 because it is a flat one time charge

We want the max to be 71 so that will be our y

71 = 6.50x + 6

We are now going to solve for x

65 = 6.5x

x = 10

From 20 tons to 99 tons? Increase or decrease?

Answers

Answer:

increase in weight

Step-by-step explanation:

Answer:

Increase.

Step-by-step explanation:

20 is larger than 99. if one ton is 2000 pounds then 20 tons are 40,000 pounds. So 99 times 2000 is 198,000 pounds, which is larger than 40,000.

Summary: 20 tons (40,000 pounds) < 99 tons (198,000) pounds

Length of x + 8 = [tex]\frac{12}{20}[/tex] × 30

x + 8 = 18

x = 18 - 8
