Final answer:
Rochelle would need to earn $220 in tips as a server to have her earnings equal to her earnings as a hostess at the restaurant (Option A).
Step-by-step explanation:
To find the equality between Rochelle's earnings as a hostess and server, we need to set up an equation. Let's assume the amount of tips she receives as a server is represented by T. The equation would be:
Hostess earnings = Server earnings + Tips
$530 = $310 + T
To solve for T, we subtract $310 from both sides of the equation:
$530 - $310 = T
Simplifying, we have:
$220 = T
Therefore, Rochelle would need to earn $220 in tips to have her earnings as a server equal to her earnings as a hostess. So, the answer is A) $220.
