Suppose a city with population 800,000 has been growing at a rate of 7% per year. If this rate continues, find the population of
djverab [1.8K]

Answer:

1,752,000

Step-by-step explanation:

1.  First you have to take the 7% and multiply that by the years whish is 17 so      that way you know your total percentage of growth which is 119%

2.  Second you then need to find how much 1% is to find out our total growth in population so you take 800,000 and divide that by 100 since there's only 100% and you get 8,000.

3.  Now you take the 8,000 and multiply that by the percentage of the growth that you have which is 8,000*119 and you get 952,000

4.  Lastly all you have to do is add the growth of the population to the population you already have so 800,000+952,000=1,752,000

A soccer stadium had a capacity of 25000 seats, but with the new area built this increased by 20%.
sergij07 [2.7K]

Answer:

19,500 people

Step-by-step explanation:

20% of 25,000 is 5,000.

Add 5,000 to 25,000 - this will give you 30,000. That is a 20% increase.

65% of 30,000 is 19,500, thus there are 19,500 people in the stadium.
