Answer:

When [tex]n\geq 50= 25n-80[/tex]

Step-by-step explanation:

If [tex]n\geq 50= 25n-80[/tex]

If the school buys n books, they purchase each book for $25, so that would be 25n

Since they're buying more than 50 books, they get a discount of $80.

So when n is greater or equal to than 50, they get a discount. which gives the expression [tex]n\geq 50= 25n-80[/tex]
