Final answer:
To find the enrollment this year, calculate 12% of last year's enrollment and add it to the enrollment from last year. The enrollment this year is 17,360.
Step-by-step explanation:
To find the enrollment this year, we need to calculate 12% of last year's enrollment and add it to the enrollment from last year.
- Calculate 12% of 15,500: 12% × 15,500 = 0.12 × 15,500 = 1,860.
- Add 1,860 to last year's enrollment: 15,500 + 1,860 = 17,360.
Therefore, the enrollment this year is 17,360.
