Final answer:
If there are over 500 hens on the farm, they would lay approximately 187.5 eggs at this rate.
Step-by-step explanation:
Dory's Grandma runs a chicken farm where the number of eggs the hens lay is given by the equation E = (3/8)H, where E is the number of eggs and H is the number of hens. To find out how many eggs they would lay if there are over 500 hens on the farm, we can substitute H = 500 into the equation:
E = (3/8) * 500 = 3 * 500 / 8 = 1500 / 8 = 187.5 eggs
Therefore, they would lay approximately 187.5 eggs at this rate.
