Answer:
Explanation:
To calculate the number of students Ms. Sheldon has this year, we need to first find 150% of the number of students she had last year.
150% of 30 students can be found by multiplying 30 by 1.5 (since 150% is the same as 1.5 times the original amount):
30 x 1.5 = 45
Therefore, Ms. Sheldon has 45 students in her class this year.
