Answer:
53 robberies
Step-by-step explanation:
Number of robberies took place last year = 62
Percentage decrease in number of robberies = 15%
So,
Number of robberies took place this year = Number of robberies took place last year - [tex]\frac{15}{100}[/tex] (Number of robberies took place last year)
= [tex]62-\frac{15}{100}(62)[/tex]
= [tex]62(1-\frac{15}{100})[/tex]
= [tex]62(\frac{85}{100})[/tex]
= [tex]\frac{5270}{100}[/tex]
= [tex]52.7[/tex]
≈ 53 robberies
