Q. In a certain town there were 213 robberies last year. This year the number of robberies has gone down 19%. How many robberies were there this year, to the nearest whole number?Answer:
Calculate Decrease in Robberies: Calculate the decrease in the number of robberies by finding 19% of last year's total.19% of 213 robberies = 0.19×213= 40.47
Subtract Decrease from Last Year: Since we are looking for the number of robberies this year, we need to subtract the decrease from last year's total.Number of robberies this year = Last year's robberies − Decrease in robberies=213−40.47However, we need to round the decrease to the nearest whole number before subtracting.40.47 rounded to the nearest whole number is 40.
Find This Year's Total: Now, subtract the rounded decrease from last year's total to find this year's total number of robberies.Number of robberies this year = 213−40= 173
