<u>Given</u>:
The number of tickets sold to children 
The number of tickets sold to adults 
The number of tickets sold to seniors 
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 
The total number of tickets sold to children, adults, and seniors 
The percentage of tickets sold to seniors 
Rounding this off, we get the value as 13.9%
Hence, option 1 is the correct answer.
Answer:
1.38 * 10^ -2
Step-by-step explanation:
.0138
We need 1 number to the left of the decimal
1.38 * 10^ something
We moved it 2 places to the right, that means our exponent is -2. If we had moved it to the left, our exponent would have been positive
1.38 * 10^ -2
