Answer:
16.3% (rounded)
Explanation:
The first step in finding the percent markdown is to subtract the sale price from the original price.
154.30 - 129.15 = 25.15
Now divide the difference by the original price.
25.15/154.30 = 0.16299
Change to a percent by multiplying by 100.
16.299
If you need to round, it is 16.3%
