Data representing the price and quantity demanded for hand-held electronic organizers were analyzed every day for 15 days. The logarithmic function of best fit to the data was found to be y= 398-73 lnx. Use this to predict the number of hand-held electronic organizers that would be demanded if the price were $275. Round to the nearest whole number. a. 6 electronic organizers
b. 5 electronic organizers
c. 4 electronic organizers
d. 7 electronic organizers
