Answer:
The discount on the barbecue grills is 75.11%.
Explanation:
To calculate the discount as a percentage, we first need to find the total discount amount by subtracting the new price of the barbecue grills from the old price. This gives us $844 - $211 = $633.
To find the discount as a percentage, we divide the discount amount by the old price and multiply the result by 100%. This gives us $633 / $844 * 100% = 75.11%.
Therefore, the discount on the barbecue grills is 75.11%.
