6. At a school supply store, the price of three

notebooks plus a $30 backpack is the same as the

price of 11 notebooks. Which of the following

equations can be used to find the price of each

notebook?

A 3x = 11x + 30

B 3x + 30 = 11x

C 30 = 3x + 11x

D 3x - 30 = 11x

Answer is b

Step-by-step explanation:

x = number of notebooks

The answer is:B

First, look for some of the key words in the word problem.

Plus, is the same as the ...

Now we can use those key words and translate it into an equation.

You don't know the price of 3 notebooks, so you should put: 3x

Instead of saying plus, we can say: +

It says " ... 3 notebooks plus a $30 backpack ... " so we add 30.

Instead of saying "is the same as the", we can say: =

You don't know the price of 11 notebooks either, so you should put: 11x

Now, put together the equation:

3x + 30 = 11x

There is your equation! Match it up with one of the given answers and you will receive B.
