Final answer:
To find the percent increase in students at MMS from last year to this year, the difference between the current and previous year's student numbers is divided by last year's number, then multiplied by 100. The calculation yields a percent increase of approximately 4.49%.
Step-by-step explanation:
The question is asking for the percent increase in the number of students at MMS from last year to this year. To calculate the percent increase, we need to find the difference in the number of students between the two years and then divide that by the number of students from the starting year (last year) before multiplying by 100 to convert it to a percent. The difference in the number of students is 720 (this year) - 689 (last year) = 31 students.
Now, the percent increase would be calculated as follows:
Percent Increase = (Difference in the number of students / Number of students last year) × 100
Percent Increase = (31 / 689) × 100
Using the equivalent fractions method, we can set this up as x/100 = 31/689, cross-multiply and solve for x, which represents the percent increase. In this case, x is approximately 4.49%, which is the percent increase in the number of students at MMS from last year to this year.
