A quantity with an initial value of 5700 decays exponentially at a rate of 7.5% every 2 days. What is the value of the quantity after 234 hours, to the nearest hundredth?

(Also how do I solve problems like this one?)

Astandard american eskimo dog has a mean weight of 30 pounds with a standard deviation of 2 pounds. assuming the weights of standard eskimo dogs are normally distributed, what range of weights would 99.7% of the dogs have? approximately 26–34 pounds approximately 24–36 pounds approximately 28–32 pounds approximately 29–31 pounds
