First simplify the expression.
1/3(1,650+0.15c)
550+0.05c
Answer is A
Hope this helps!
To solve this question, we need to solve an exponential equation, which we do applying the natural logarithm to both sides of the equation, getting that it will take 7.6 years for for 21 of the trees to become infected.
Model:
The exponential model for the number of infected trees after t years is given by:
How many years will it take for 21 of the trees to become infected?
This is t for which:
Thus
Applying the natural logarithm to both sides:
It will take 7.6 years for for 21 of the trees to become infected.
