Final answer:
The 18% off discount is the better option.
Step-by-step explanation:
To determine which option is better, we need to compare the value of the rebate and the value of the 18% off discount. Let's calculate the values of each:
Option 1: Rebate = $2,000
Option 2: 18% off = 18% * $13,000 = $2,340
Since $2,340 is greater than $2,000, the 18% off discount is the better option.
