To find the answer, we first must write an equation.
($17.90+(X Notebooks)) + 6% Sales Tax = $30.74
Now, we solve the equation for X.
First, we have to find the total before the sales tax. To do this, we divide the total by 1.06
$30.74/1.06= $29
Now, we subtract the cost of the backpack and solve for X
$17.90+X=$29
X=11.10
Given that X is the total of 6 Notebooks, we divide $11.10 by 6 to find the price for each Notebook.
$11.10/6=$1.75 per notebook
It costs $1.85 for each notebook before sales tax and $1.96 after sales tax.

Carl's cable company charges $55 for monthly service plus $4 for each pay-per-view movie. Teleview cable company charges $110 pe
shusha [124]
Let us assume the number of movies for ehich the cost of both companies becomes the same = x
Then
55 + 4x = 110
4x = 110 - 55
4x = 55
x = 55/4
   = 13.75
So
The number <span>number of movies for which the cost of Carl's cable company is less than the cost of Teleview = 13.

I hope the procedure is clear enough for you to understand and this is the answer that you were actually looking for.</span>
