Question

the population of city A is 18% less than the population of city B. If the population of city b is 10,000 what is city A populations?

Answer 1

the population is 8,200

Explanation:

x/10,000 = 18/100 (Cross multiply)

100x = 10,000(18)

100x = 180,000

100x/100 = 180,000/100

x = 1,800

10,000 - 1800 = 8,200
