Answer:
10% of the total tickets was not sold
Step-by-step explanation:
Total number of seats in the stadium =Total number of tickets produces=30000
Total ticket sales=Cost per ticket×Number of tickets sold
where;
Cost per ticket=$55
Number of tickets sold=N
Total ticket sales=$1,485,000
Replacing in the expression above;
$1,485,000=55×N
N=1,485,000/55
N=27,000 tickets
Number of tickets sold=N=27000 tickets sold
Total number of tickets=Total tickets sold+Total tickets unsold
where;
Total number of tickets=30000
Total tickets sold=N=27000
Total tickets unsold=S
Replacing;
30000=27000+S
S=30000-27000
S=3000 tickets unsold
Percentage of tickets unsold=(Number of tickets unsold/Total number of tickets)×100
(3000/30000)×100=10%
10% of the total tickets was not sold
