Mason compares two plans for an online book club. Which equation can be used to solve for the number of books, b, for which the cost of Plan A equals Plan B?
12b = 75b + 3
12b = 3b + 75
12 + 3b = 75

The correct equation to use for solving the number of books, ( b ), for which the cost of Plan A equals Plan B is:
12b = 3b + 75
Explanation: This equation sets the total cost of Plan A, which we assume is based on a cost of 12 multiplied by the number of books, equal to the total cost of Plan B, which includes a fixed cost of 75 and a variable cost represented by 3 for each book. By solving this equation, we can find the number of books where the costs are equal.
