What percentage of tickets sold were to seniors?
Kay [80]

<u>Given</u>:

The number of tickets sold to children =35+87+62=184.

The number of tickets sold to adults =56+177+205=438.

The number of tickets sold to seniors =32+14+54=100.

To determine the percentage of tickets sold to seniors we need to determine the total number of tickets sold to each category.

<u>To determine the percentage of tickets sold to seniors:</u>

In order to determine the percentage of tickets sold to the seniors, we divide the tickets sold to seniors by the total number of tickets sold to children, adults, and seniors.

This value is multiplied with 100 to convert it into a percentage.

The number of tickets sold to seniors =100.

The total number of tickets sold to children, adults, and seniors = 184+438+100=722.

The percentage of tickets sold to seniors = \frac{100}{722} (100) = 0.1385(100)=13.85\%.

Rounding this off, we get the value as 13.9%

Hence, option 1 is the correct answer.
