A friend bought 2 boxes of pencils and 8 notebooks for school and it cost him $11.he went back to the store the same day to buy school supplies for his younger brother . he spent $11.25 on a boxes of pencils and 5 notebooks. how much would the notebook coast?
Joanna went school supply shopping. She spent $36.36 on notebooks and pencils. Notebooks cost $2.47 each and pencils cost $1.06 each. She bought a total of 21 notebooks and pencils. How many of each did she buy?
To find out how much 7 notebooks would cost, we need to determine the cost of one notebook.
Let's first calculate the cost of one box of pencils:
From the first scenario, we know that 2 boxes of pencils and 8 notebooks cost $11.
If we subtract the cost of 8 notebooks, we can determine the cost of 2 boxes of pencils.
$11 - cost of 8 notebooks = cost of 2 boxes of pencils
Next, we can calculate the cost of one box of pencils by dividing the total cost of the 2 boxes by 2:
cost of 2 boxes of pencils / 2 = cost of one box of pencils
Using the same approach, we can calculate the cost of one notebook. We have the cost of 2 boxes of pencils and the cost of 8 notebooks in the first scenario, so:
cost of 2 boxes of pencils + cost of 8 notebooks = $11
cost of 2 boxes of pencils + 8 * cost of one notebook = $11
cost of one notebook = ( $11 - cost of 2 boxes of pencils ) / 8
Now that we know the cost of one notebook, we can find out how much 7 notebooks would cost:
cost of 7 notebooks = cost of one notebook * 7
