To represent the situation with an inequality, we can let \( n \) be the number of notebooks Emily wants to buy. Since each notebook costs $5, the total cost for \( n \) notebooks would be \( 5n \).
Emily has a budget of $15, so we want the total cost not to exceed her budget. This gives us the following inequality:
\[
5n \leq 15
\]
This inequality represents the situation where Emily can buy notebooks without exceeding her budget. To find out how many notebooks she can buy, we can solve this inequality:
1. Divide both sides by 5:
\[
n \leq 3
\]
Thus, Emily can buy a maximum of 3 notebooks without exceeding her $15 budget.
