Consider the following two monetary incentives when purchasing a desktop computer at the regular price of $299

To calculate the final price of the incentives, we need to calculate the discount and subtract it from the regular price.

For the first incentive, the discount is 25% off. So the discount amount is 25% of $299, which is (25/100) * $299 = $74.75
Therefore, the final price after the 25% discount is $299 - $74.75 = $224.25

For the second incentive, the rebate is 70% on a purchase of $2000 or more. Since the price of the desktop is $299, it does not meet the condition of the rebate. So, there is no rebate applicable in this case.
Therefore, the final price after the rebate is $299.

Comparing the final prices, the better incentive is the 25% discount, resulting in a final price of $224.25.
