Kyle wants to purchase 20 prefilled decorated eggs to set up an egg hunt for his nephews and nieces. Each egg is priced at $5.00, and the store offers two different incentives.

• Incentive 1: Purchase any set of 3 prefilled eggs for $12.
• Incentive 2: Take 20% off your entire purchase
Determine whether incentive 1 or incentive 2 offers a better discount. Find the discount amount. Round the answer to two decimal places as necessary.

For incentive 1, Kyle would need to purchase the eggs in sets of 3. Since there are 20 eggs in total, he would need to purchase 20/3 = 6 sets of 3 eggs.

Each set of 3 eggs costs $12, so Kyle would spend a total of 6 * $12 = $<<6*12=72>>72.
For incentive 2, Kyle would receive a 20% discount on his entire purchase.
The discount amount would be 20% * $100 = $<<20*.01*100=20>>20.
Therefore, incentive 2 offers a better discount with a discount amount of $20. Answer: \boxed{20}.
