A hardcover book sells for 24$ at the bookmart. Ben pays 25.02 for the book. What is the sales tax rate?

Answers

Answer 1

Answer: The sales tax rate would be 5 percent.

Take the 5 and turn it to a decimal, 0.05.

Times that by 24. 0.05×24= 1.2

That equals out to 1.2, but since we're talking about money we have to add the zero at the end. 1.20.

Now add the 1.20 to 24.

24+1.20= 25.02.

hope this helps!

Answer:

The number of solutions of the equation is:

One.

Step-by-step explanation:

We are asked to find the number of solutions of the equation:

3x+6= -1-3+4x

(

We know that a expression has a unique or one solution if it gives a single value of x after solving the expression.

and we obtain a no solution when the equation gives a false result i.e. the left and right hand side of equality are different.

and infinite many solution if the left and right hand side of equality is same but we can't get a fix value of x )

Now on solving the expression we have:

3x+6= -4+4x

i.e. 4x-3x=6+4

i.e. x=10

Hence, we get a unique value of x.

Hence, the equation has one solution.

it has One solution and to get it solve the equation for x :
6+1+3=4x-3x
x=10

Which shows the equation c=a(w/150) correctly solved for the variable w ?

Answers

$c=a( (w)/(150) )$

$c=a* (w)/(150)$ $Simplify \ brackets$

$c= (aw)/(150)$

$c*150=aw$ $Multiply \ both \ sides \ by \ 150$

$150c=aw$    $Regroup \ terms$

$(150c)/(a) = w$    $Divide \ both \ sides \ by \ a$

$w= (150c)/(a)$    $Solution$

Final answer:

To solve the equation c = a(w/150) for 'w', divide the equation by 'a' and then multiply by 150. This gives us w = 150c/a. This equation represents 'w' in terms of 'c' and 'a'.

Explanation:

To solve the equation c = a(w/150) for the variable w, you need to isolate w on one side of the equation. The goal is to express w in terms of c and a.

First, divide both sides of equation by a. This gives you c/a = w/150.
Then, multiply both sides by 150 to solve for w. This results in w = 150c/a.

So, the equation solved for w is w = 150c/a.

Wow ! If I understand what's go0ing on here, then
we have to be careful, and THINK .

I was going to ask you "What does Ф mean ?", and then I realized,
Ф is a new operation that the teacher invented.

The first line on the board is the definition of Ф .

Ф means "Add the two numbers and subtract 4."

Now you have to use this new invention to find the value
of the second line:

Take care of the stuff inside the parentheses first: ( 4 Ф 2 )
Add the two numbers and subtract 4
4 + 2 - 4 = 2
That's the part inside the parentheses. It's 2 .

NOW, we have to do the new operation with the 2 inside,
and the 3 that's outside the parentheses:

3 Ф 2
Add the two numbers and subtract 4
3 + 2 - 4 = 1

And that's the final value of 3 Ф (4 Ф 2) . It's 1 .

Pretty sneaky.

The correct answer I got was 1
