Determine which of the following is the better incentive offered on a wireless computer keyboard at the regular price of $24.99: 20% off, or a $6 rebate

To determine which incentive is better, we need to calculate the amount of money saved for each option.

Option 1: 20% off
20% of $24.99 = $0.2 * 24.99 = $4.998

Option 2: $6 rebate

Comparing the two options, we can see that the $6 rebate saves more money than the 20% off. Therefore, the better incentive offered on the wireless computer keyboard is the $6 rebate.
