The answer to the questions
So the equation you'll use is (18,000 × .041)y+18000. Y is your years which is 20. So all you need to do is plug it in to get (18,000 × .041)20+18000 and when solved is 32,760 downloads by 2030
so if you do 9 divided by 60 and it will give you 0.15 and that is your answer
1/5 of 200 is 40 which mean she gave 40 away and she has a 160 left
