In chemistry, the acidity of a solution is measured using the pH scale 0-14. A solution that's pH 3 is 10 times more acidic than a solution that's pH 4. The lower the pH the more acidic something is. The higher the pH the more basic something is. Water is generally around pH 7 (calculated using logarithms)

Also, in seismology. <span>Vibrations are picked up and plotted on a seismograph. The strength, or magnitude, of an earthquake is measured using the Richter scale. The Richter scale is numbered 0-10. </span><span> </span><span>So an earthquake thats a 5 on the Ricter scale is 10 times stronger/bigger than one that's a 3. (Logarithms) </span> --------------------------------------------------------- <span /> Biologists that calculate population growth, whether animal, human or microorganism. When organisms create more organisms in a population they grow exponentially. (exponential functions)
Also, a lot of financial things like compound interest on a saving account or loan. (exponential function)
I would say that the correct answer that best defines the two quantities that are measured to find the call rate of a phone company is A. the quantity of price measured in dollars depends on the quantity of time measured in minutes.
