Final answer:
Julia can purchase a maximum of 8 earrings.
Step-by-step explanation:
To find the maximum number of earrings Julia can purchase, we need to determine how much money she has left after buying the paint set.
Given that Julia starts with $80 and the paint set costs $16, her remaining budget can be calculated as $80 - $16 = $64.
Since each pair of earrings costs $8, Julia can purchase the maximum number of earrings by dividing her remaining budget by the cost per pair: $64 / $8 = 8 earrings.
