Question

The population of a city went up by 4% last year to 478,400. What Was the population beside the increase

Answer 1

before the increase the population was 287,040. 4% of 478,400 is 191,360 so you would just subtract 191,360 from 478,400 and you get 287,040. to find 4% of 478,400 you multiply 478,400 by 0.4 and you get 191,360.
