Suppose a city with population 300,000 has been growing at a rate of 5% per year. If this rate continues, find the population of this city in 12 years

538,757

Step-by-step explanation:

Population=(current population)*(1+rate)^(year)

Population=(300000)*(1+5/100)^12=538,756.899 or 538,757. Love from Gauthmath

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
