0.30 + x + 2x = 6.75

Solve for x.

3.22

To find out how much each notebook costs, let's assign variables.

Let's say the cost of one notebook is 'x' dollars. Since the other notebook costs twice as much, its cost will be '2x' dollars.

We know that Jenifer bought 2 notebooks and a pencil, and the pencil cost $0.30. So, the total cost of the notebooks will be 2x dollars, and the total cost of all items will be 2x + $0.30.

We also know that Jenifer spent a total of $6.75. Therefore, we can set up the equation:

2x + $0.30 = $6.75

To find the value of 'x,' we can subtract $0.30 from both sides of the equation:

2x = $6.75 - $0.30
2x = $6.45

Now, to find the value of 'x,' we can divide both sides of the equation by 2:

x = $6.45 / 2
x = $3.225

So, one notebook costs $3.225.

Since the other notebook costs twice as much, its cost would be:

2x = 2 * $3.225
2x = $6.45

Therefore, the other notebook costs $6.45.

Thus, one notebook costs $3.225 and the other notebook costs $6.45.
