Yearbook Photography Total
Girls
18 31
Boys 12
26
Total 25
What percentage of students would prefer to take photography? Round your answer to the nearest tenth of a percent.
%

Answer 1

Let's first fill in the missing values in the table based on the data given.

We know the totals for the rows and columns:

1. For Girls:
- Yearbook: 18
- Photography: \(31\) (given)

The total number of girls is \(18 + 31 = 49\).

2. For Boys:
- Yearbook: \(12\) (given)
- Photography: (unknown)

We know the total for Boys is \(26\), so:
\[
12 + \text{Photography} = 26 \implies \text{Photography} = 26 - 12 = 14.
\]

Now we can fill in the table:

| | Yearbook | Photography | Total |
|-----------|----------|-------------|-------|
| Girls | 18 | 31 | 49 |
| Boys | 12 | 14 | 26 |
| Total | 30 | 45 | 75 |

Now we find the total number of students:
- Total number of students = Total girls + Total boys = 49 + 26 = 75.

Next, we need to find the total number of students preferring Photography:
- Total Photography = Girls Photography + Boys Photography = 31 + 14 = 45.

Now, we can calculate the percentage of students who would prefer Photography:
\[
\text{Percentage of students preferring Photography} = \left( \frac{\text{Total Photography}}{\text{Total students}} \right) \times 100 = \left( \frac{45}{75} \right) \times 100.
\]
\[
= 0.6 \times 100 = 60\%.
\]

Therefore, the percentage of students who would prefer to take photography is **60.0%** (rounded to the nearest tenth of a percent).
