Single Equivalent Discount % on final price = 41.58%
Explanation:
The grill was initially priced at $769.99 and was discounted to $550.54 which is 28.5% ((550.54/769.99)-1)*100
and then further discounted by 18.3% ((449.79/550.54)-1)*100 to $449.79.
but if we want to get the single discount rate for $449.79 (final price), we have to compare it with very first original price of $769.99 so the formula will be:
((449.79/769.99)-1)*100 = 41.58% which shows the actual discount % versus the original price of the grill.
