A school buys pens and pencils from a supplier. The supplier charges $0.05 for each pencil and $0.25 for each pen. The school pays $440 for the pens and pencils.If the school bought 1500 pencils, how many pens did the school buy?

Hi there! The answer is 1460 pens

The school pays $440 for the pens and pencils.
If the school bought 1500 pencils, their total expense on pencils can be found by multiplying the amount of pencils, by the price per pencil.

[tex]1500 pencils \times 0.05 = 75[/tex]
Therefore, the total expense on pencils is $75. Now we can calculate that there is $440 - $75 = $365 left for buying pens.

To finally find the amount of pens bought, we need to divide our remaining budget by the price per pen.

[tex]365 : 0.25 = 1460[/tex]
Hence, the school bought 1460 pens.
