1. Ross Geller is the owner of New Yorks Dinosaur Museum. He has hundreds of tourists that visit his museum on a daily basis. Ross has decided to make his business more efficient to only sell tickets online. This requires his customers to pre-order tickets before they visit. Ross believes allows for faster entry and no line ups at the door. He charges $35 for each adult and $20 for children. His hours of operation are 9am to 6pm Monday to Friday and 10 am to 8 pm on Saturday and Sunday. On February 3, 2021 he checked his website and saw that 300 adults and 120 children would be visiting the museum today. At 8:45 am the fire alarm went off due to a fire in a portion of the building. The fire department arrived and told Ross the building was not safe and needed to be closed the rest of the day. Ross recorded his sales the same way he always does that day
