Final answer:
To find the number of seventh-grade students, we need to determine how many students voted for Blake. We know that three-fourths of the students voted for him, so we can find the number of students who voted by multiplying three-fourths by the total number of students. The total number of seventh-grade students could be option A: 300.
Step-by-step explanation:
To find the number of seventh-grade students, we need to determine how many students voted for Blake. We know that three-fourths of the students voted for him, so we can find the number of students who voted by multiplying three-fourths by the total number of students.
Let's set up an equation to solve for the number of seventh-grade students: 3/4 * Total number of students = Number of students who voted for Blake
We are given that Blake needed at least 225 votes, so we can set up another equation: Number of students who voted for Blake ≥ 225
By substituting the first equation into the second equation, we get: 3/4 * Total number of students ≥ 225
To solve for the total number of students, we divide both sides of the inequality by 3/4: Total number of students ≥ 225 ÷ (3/4)
Therefore, the total number of seventh-grade students could be option A: 300.
