Please help me with algebra 2. Still struggling to finish this year strong.. Any help appreciated. Thank you.?

One weekday, the ticket salesperson at a bus station asks every 10th ticket buyer if he or she had planned to use a laptop computer while traveling. Of the 145 travelers questioned, 54 said yes. Based on this sample, which is the best prediction for the number of the regular 3100 weekday bus travelers that use a laptop while traveling?
