1) =total seats =32560 give away tickets=4500 amount of each ticket=$9.50 each to get the remaining ticket you subtract give away tickets from total seats =32560-4500 =28060 remaining tickets are=28060 so you multiply remaining tickets by the amount they sold each of the tickets =28060×$9.50 =$266570 so the answer is $266570 2) paperback book is sold for = 25¢ each hardcover book is sold for=$1.25 each total number of the paperback book = 54 total number of the hardcover book =163 so you need to multiply paperback book by the amount it sold each and you still do the to hardcover book =25¢×54=$13.5 =$1.25×163=$203.75 then we add the the total together = =$203.75+$13.5= $217.25 so the answer is $217.25 3)$14.50 per hour if she works for 35hours she gains extra $1.5per hour if she works 48 hours we are going to subtract 35 hours from 48 hours to get the extra time she worked =48-35= 13 so we multiply 13 by $1.5 =$19.5 so we multiply 14.50by 35= $507.5 so we add = $507.5+$19.5= $527 so the answer is $527 4) airfare is $398.60 her room is $115.70 per night ×2 cab =$40 add up =$398.60+$231.4+$40=$670.00 so the answer is $670.00
