Final answer:
To find the number of posters that can be printed within a budget of $300, set up the inequality $60 + $2x <= $300 and solve for 'x'.
Step-by-step explanation:
To find the number of posters that can be printed within the budget of $300, we need to set up an inequality. Let's assume the number of posters to be printed is 'x'. The cost of printing 'x' posters would be $60 + $2x. We can set up the inequality as follows:
$60 + $2x <= $300.
Now, we can solve this inequality to find the maximum number of posters that can be printed.
