In the 1940s, behavioral psychologist Robert Tryon conducted an experiment in which rats were placed in a complex maze that had a food reward at one exit. Rats that made fewer errors navigating the maze were bred together to create a “maze-bright colony.” Rats that made more errors were bred together to create a “maze-dull colony.” After selectively breeding the mice for seven generations, Tryon tested offspring from each colony to determine how quickly those rats would learn the maze. Offspring of the maze- bright rats consistently made fewer errors than the maze-dull offspring. Tyron’s research therefore suggests that the ability to navigate the maze successfully was influenced by genes passed from parent to offspring.

A bank loaned out $19,500, part of it at the rate of 3% annual interest, and the rest at 2% annual interest. The total interest earned for both loans was $535.00. How much was loaned at each rate? $ was loaned at 3% and $ was loaned at 2%.
