Answer :
To solve this question, we need to calculate the decrease in the number of pediatricians and then subtract that decrease from the original number to find out how many pediatricians are there this year.
Let's follow the steps to calculate it:
1. Calculate the decrease in the number of pediatricians in terms of percentage.
If there is an 18% decrease, we convert this percentage to a decimal by dividing by 100, which gives us 0.18.
2. Calculate the decrease in terms of the number of pediatricians.
To find the actual number decrease, we multiply the original number of pediatricians by the decimal form of the decrease percentage.
Number of pediatricians decreased = 2000 0.18
3. Perform the calculation.
2000 0.18 = 360
4. Subtract the decrease from the original number of pediatricians to find the number of pediatricians this year.
Number of pediatricians this year = 2000 - 360
5. Perform the subtraction.
2000 - 360 = 1640
So, there are 1640 pediatricians this year after a decrease of 18% from the previous year. Therefore, the correct answer is 1640.
