Question

a total of 17100 seats are still available for the next hockey game.if 62% of the tickets are sold how many seats are in the arena

Answer 1

If 62% of the seats are sold; 

100-62= 38% seats still available. 

17100=38% seats available

17100/38= seats in 1%
450 seats

In 100%, 
450×100=450000 seats total. 

Hope I helped :)
