Mrs. Diaz needs a new whiteboard for her classroom. She can buy it from Office Supply for $49.99 with a 15% teacher discount, or from Office Wholesale for $47.99 with a $10 rebate. Find the final price that Mrs. Diaz has to pay for the whiteboard after the better incentive is applied. Round the answer to two decimal places.

Answer 1

The teacher discount at Office Supply is equal to $49.99 * 0.15 = $7.50.
After the discount, Mrs. Diaz would pay $49.99 - $7.50 = $42.49 at Office Supply.
After the rebate, Mrs. Diaz would pay $47.99 - $10 = $37.99 at Office Wholesale.
Hence, Mrs. Diaz should buy the whiteboard from Office Wholesale, and she will have to pay $37.99. Answer: \boxed{37.99}.
