Thank you for the opportunity to help you with your question!

1. total seats=900

ratio is 11:1

total ratio =12

ticket sold=1/12 x 900

=75 tickets was sold

2.principle =2200 ,time=1.5 years rate =8%

Interest=principle x rate xtime/100

2200 x 0.08 x1.5

=264

total amount =principle + interest

264+2200

=2464
