Answer:
Getting 20% off is the best choice as it is the only deal that fits within the budget.
Explanation: Here are the details:
The dining set originally costs $1,500.
If a 20% discount applies,
The discount value on the dining set = 20% of 1500
= $300
Thus, after applying the 20% off, the total cost of the dining set = 1500 - 300 = 1200, which is below $1,250.
Hence, it is within the budget.
Conversely, with the $200 rebate,
The adjusted price becomes 1500 - 200 = $1,300, which exceeds $1,250.
Thus, it is out of budget.
Likewise, with the $150 coupon,
The new price will be 1500 - 150 = $1,350, also exceeding $1,250.
Consequently, it does not remain within the budget.
