Q: A frog lays 800 eggs a year. 10 percent dry up, and 70 percent are eaten. 1/4 of the remaining eggs end up hatching, how many frogs hatch out of the 800?
A: 40
Step-by-step reasoning process: Dried up:800(.10) = 80 eggs. 800(.70) = 560 eggs. Total left:800 - 80 - 560 = 160 eggs. 160 / 4 = 40 eggs survive to hatch.
