Given the statement:
The population of bears in a protected area is 374.
Determine the population increase if the rate increase by 18.8% per year.
Solution:
In order to determine the new population,we simply needed to multiply 374 by the decimal value of 18.8%. In converting a percentage into decimal, divide the percentage by 100, hence in converting a decimal to percentage, multiply the percentage by 100.
= 18.8/100
= 0.188
= (0.188)(374)
- = 70.3 or 70 (Since we cannot take decimal values)
Add 70 to 374 in order to determine the new population.
= 70 + 374
= 444
Final answer:
The new bear population is 444.
