Kyle wants to purchase 23 field decorated eggs to set up for his egg hunt nephews. And nieces, each egg is priced at five dollars and the store offers two different incentives

The store offers two different incentives for purchasing the eggs. Let's call the first incentive "Buy 4, Get 1 Free", which means for every 4 eggs purchased, Kyle will get 1 egg for free.

Since Kyle wants to buy 23 eggs, he will have to take into account the number of free eggs he will receive. For every 4 eggs purchased, he will get 1 egg for free.

So, 23 eggs divided by 4 gives us 5 sets of 4 eggs, with 3 remaining eggs.

Therefore, Kyle will have to pay for 23 - 5 = 18 eggs.

The price for each egg is $5, so Kyle will have to pay 18 * $5 = $<<18*5=90>>90 for the 18 eggs.

The second incentive offered by the store is a "10% discount on a purchase of 20 or more eggs". Since Kyle is purchasing 18 eggs, this incentive does not apply in this case.

Therefore, Kyle will have to pay the full price of $90 for the 18 eggs.
