Janet’s ducks lay 16 eggs per day. She eats three for breakfast every morning and bakes muffins for her friends every day with four. She sells the remainder at the farmers' market daily for $2 per fresh duck egg. How much in dollars does she make every day at the farmers' market?

Answer: Janet makes $18 every day at the farmers' market.

Step-by-step solution

Step 1: Calculate total eggs used daily

First, we need to find out how many eggs Janet uses daily for her own consumption and for baking muffins. This will help us determine the number of eggs she has left to sell.

Step 2: Substitute values and calculate eggs used

Janet eats 3 eggs for breakfast and uses 4 eggs for muffins. Adding these quantities together gives us the total number of eggs used daily.

Step 3: Calculate remaining eggs to sell

Next, we subtract the eggs used (for breakfast and muffins) from the total number of eggs laid by the ducks to find out how many eggs are left to sell at the farmers' market.

Step 4: Substitute values and calculate eggs to sell

Janet's ducks lay 16 eggs per day, and she uses 7 eggs. Subtracting 7 from 16 gives us 9 eggs that she can sell.

Step 5: Calculate daily earnings from selling eggs

Finally, to find out how much money Janet makes, we multiply the number of eggs she sells by the price of each egg.

Step 6: Substitute values and calculate daily earnings

Janet sells 9 eggs at $2 per egg. Multiplying these values gives her total daily earnings from the farmers' market.
