Final answer:
There are 250 seventh-grade students at Mountain Park Middle School, 32% of whom are in advanced math. First, calculate 32% of 250 to determine how many students are in advanced math (80 students), and then subtract that number from the total to find the number of students not in advanced math (170 students).
Step-by-step explanation:
The student is asking to find out how many seventh-grade students at Mountain Park Middle School are not in advanced math if there are 250 seventh-grade students and 32% are in advanced math. To solve this, we first need to calculate 32% of 250, which will give us the number of students in advanced math. Then, we subtract that number from the total number of students to find the number of students who are not in advanced math.
To begin with, the calculation for the number of advanced math students is:
Number of advanced math students = 32% of 250
= 0.32 × 250
= 80 students
Now, the equation to represent the number of seventh-grade students who are not in advanced math is:
Number of students not in advanced math = Total number of students - Number of advanced math students
= 250 - 80
= 170 students
Therefore, the equation can be written as:
170 = 250 - 80
