Answer:
a) 35%
b) 6.67%
Step-by-step explanation:
a) The annual number of burglaries in 2012 would be 150% and since in 2013, it fell by 10%:
10% of 150 is 15 so 150-15 = 135%.
The actual percentage increase of burglaries is 135% - 100% = 35% not 40%.
b) In the second year, the percentage would have to decrease by 10% of the initial 150% so =
which as a percentage would be 6.66666....% or 6.67%.

Value of m is equal to :
➢ 15 = 2m - 9
➢ 15 + 9 = 2m
➢ 2m = 24
➢ m = 24 ÷ 2
➢ m = 12
