Answer:
10.14 years
Step-by-step explanation:
The following equation describes the percentage of all eligible voters that are registered to vote as a function of time:
V=100-30e^{-0.04t}
The time 't' for which V(t) = 80 is the amount of years required for the percentage of registered voters to reach 80%:
80=100-30e^{-0.04t}\\\frac{20}{30}= e^{-0.04t}\\ln(\frac{2}{3})=-0.04t*ln(e)\\ t=10.14\ years
It will take 10.14 years until 80% of all eligible voters in your county are registered to vote

<em>Answer:</em>
The Answer is 300
<h3><em>
Step-by-step explanation:</em></h3>
The answer is 300 because if you look at the hundreds place it is 200 and as my teacher told me, if the number to the right is 5 or greater bump the number up! Since the number is eight the eight will move the two up one digit causing it to be 3 and since that number was moved up all the other numbers become zeros.
So, your answer is 300 or 300.00
