The formula is A=p(1 + (r/n))^(nt)
A = 3500(1 + (.08/4))^(4*2)
A = 3500 ( 1.02)^8
A = $ 4100.81
Answer:
18
Step-by-step explanation:
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.
yes I well help you, the answer is 4,–3,–3
