$13,475 was made during the first 2 hours
1) find 20% of 350 and add it to 350 to find the # of ppl who purchased tickets in the 2nd hour
420 people purchased tickets in hour 2
to find the total # of ppl who purchased tickets add 420 to 350
770 ppl purchased tickets in the first 2 hours
now multiply 770 with 17.50 to find the total money made
