Answer:
Step-by-step explanation:
20% discount makes the price $58. Sales tax brings this to $61.77.
On the website the cost is 54.75×1.09+5.99=$65.6675 for each pair.
The difference is exactly $3.8975 or $3.90 if working to the nearest cent.
For 12 pairs the difference in cost is $46.77 or $46.80 respectively.
