A coat normally costs $100. First, there was a 20% discount. Then, later, it was marked down 30% off of the discounted priced. How much does the coat cost now?

Calculate discounted price:
Discounted Price = Full Price * (1 - Discount Percentage)
Discounted Price = 100 * (1 - 0.20) <-- Since 20% = 0.2
Discounted Price = 100 * (0.80)
Discounted Price = 80

Now calculate marked down price off the discount price:
Markdown Price = Discount Price * (1 - Markdown Percentage)
Markdown Price = 80 * (1 - 0.30) <-- Since 30% = 0.3
Markdown Price = 80 * (0.70)
Markdown Price = 56
