1. In a chemistry experiment for Wallow high schoolers, Amy only had a percentage error of 3% when measuring the chlorine content in a sample of water. The accepted value for chlorine content in this experiment was 32.5%. Find Amy's experimental value given these two values.

2. William and his colleagues decided to run a laboratory experiment to determine who could get closer to the accepted value for the speed of sound at sea level, which is 340.29 meters per second. When William ran the experiment, he got 341.33 meters per second. What was his percentage error?
