Answer this question:Rhea buys 2 trays of eggs every week for her family. Her son and daughter eat 2 eggs every morning, and Rhea and her husband eat 4 eggs every night. If each tray has 24 eggs, how many eggs are not being eaten every week?
Rhea buys a total of 24 x 2 = 48 eggs every week. Her son and daughter eat 2 x 7 = 14 eggs every week. Rhea and her husband eat 4 x 7 = 28 eggs every week. So, the total eggs they eat is 28 + 14 = 42. Therefore, the total number of eggs that are not being eaten is 48 - 42 = 6.
The answer is 6.

Answer this question:In Fred the Farmer's barn, there were 100 horses, 29 sheep, and 9 chickens. Brian bought half of the animals and sold them at the market. Jeremy then gifted Fred an additional 37 goats. If exactly half of the animals in the barn are male animals, how many male animals are there in the barn?
Fred's barn started with 100 + 29 + 9 = 138 animals. Brian bought half of these, so there were 138 / 2 = 69 remaining. After Jeremy gifted Fred 37 goats, there were 69 + 37 = 106 animals in the barn. So, 106 / 2 = 53 of these animals are male.
The answer is 53.
