Answer:
1551
Step-by-step explanation:
To find out how many students were in the school last year, we can use the following formula:Previous year's number of students = Current year's number of students / (1 + percentage increase)Plugging in the provided values:Previous year's number of students = 1643 / (1 + 6%)Solving for the percentage increase:6% can be written as 0.06 (6% ÷ 100%)So, the formula becomes:Previous year's number of students = 1643 / (1 + 0.06)= 1643 / 1.06≈ 1550.94Rounding to a whole number, the approximate number of students in the school last year was 1551. Therefore, there were approximately 1551 students in the school last year.
