The population of a city has increased by 36% since it was last measured. If the current population is 51000 , what was the prev

PilotLPTM [1.2K]

So if we have the number after the 36% increase in population, we would want to subtract that 36% from 51000.

36% of 51000 can be found by multiplying 51000 by 0.36 (0.36 is the decimal equivalent of 36%)

51000 x .36 = 18360

So you simply subtract 18360 from 51000, which is 32,640.
