Nikki gathered data about the length of time she spent listening to the radio and the number of commercials she heard. She organ
ized the data in a scatter plot, where x represents the minutes spent listening and y represents the number of commercials. Then she used the graphing tool to find the equation of the line of best fit: y = 0.338x − 1.387. Based on the line of best fit, for approximately how many minutes will Nikki need to listen to the radio to hear 20 commercials? A=10
b=55
c=63
d=72
