Atthe end of May, the crime rate is rising by?crime(s) per month. Simplify your answer.)

Explanation / Answer

In a town of 200000 people, the crime rate ( C ) is given by C = (1/10)(T-65)2 +100, where T is the average temperature in 0 F during the month. Further, the average temperature during the month of May was 750 F so that the crime rate in May was (1/10) (75-65)2+100 = (1/10)*100+ 100 = 110. Also, the average temperature during the month of June was (75+6)0 F=810 F so that the crime rate in June was (1/10)(81-65)2 +100 =(1/10)*256 +100 = 125.6. Thus, the rise in crime rate at the end of May is [(125.6-110)/110]* 100 % = 14.18 % ( on rounding off to 2 decimal places).
