A university organizes an event in which all tenth-grade students from three school districts are invited to visit the university campus. Each school district serves students from kindergarten through twelfth grade. The organizers expect 10% of the invited students to attend.
Part A.
Write an equation that can be used to predict the total number of tenth-grade students expected to attend. Describe the assumptions you used to determine your equation.
Enter your equation and your work in the space provided
Let x be the total number of tenth-grade students from the three school districts. Since the organizers expect 10% of the invited students to attend, the equation to predict the total number of tenth-grade students expected to attend is:
0.10x = Total number of tenth-grade students expected to attend
In this equation, we are assuming that 10% of the invited tenth-grade students from all three school districts will attend the event.
