It will take 2 year the population to reach 300 students.
What is rounding to the nearest tenth?
Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5. To the nearest tenth, 4.6, for instance, is 4.624.
Given that, the initial number of students is 242.
The student population is growing at 12% a year.
The number of students that increases is 300 - 242 = 58.
Applying formula
I = PRT
I = The number of students that increased = 58
P = initial number of students = 242
T = Time
R = rate of increasing =12% = 0.12
Therefore,
58 = 242 × T × 0.12
T = 58/(242 × 0.12)
T = 1.997
T = 2.0 years
