Step-by-step explanation:
please tell me if I am incorrect
<span>There are 60 seconds in a minute.
To find out how many copies in a second, divide 36 by 60.
That is 0.6
Then you would calculate to see how much in 15 seconds,
0.6 times 15
9 copies in 15 seconds
then multiply 36 * 4 to see how many in minutes
144 copies in 4 minutes
153 copies in 4 minutes and 15 seconds.
Hope this helps :)

The formula for exponential growth is y=a(1+r)
. Where a is the initial value when time is 0 (100 in this case). r is the growth rate, we can see that the growth is 10%. And x is how much time has passed, we want to find out how many trucks after 9 years.
So we would plug the values in to get y=100(1+.1)
. Solving this gives us 235.79, so we would round up to 236, and our answer would be 236 trucks registered in the city in year 9.
Edit: The x and the 9 are exponents, the formatting made them look a bit weird.
They were all military officers.
