The number of minutes remaining in the poultry's temperature zone is; 3 hours and 45 minutes
<h3>How to find the temperature zone?</h3>
We are told that On the counter is poultry that has been left at a temperature of 17.5 °C for 15 minutes.
Converting 17.5°C into Fahrenheit equals 63.5 °F. This temperature in degrees Fahrenheit is within the danger zone. Now, hot food can be held in the danger zone for 4 hours. Due to the fact that the food has been on the counter for 15 minutes already, it means that it can be held on the counter for another 3 hours and 45 minutes before it becomes unsafe.

Answer:
7 years 11 months
Step-by-step explanation:
The future value formula for the value of a principal P invested at annual rate r compounded n times yearly for t years is ...
FV = P(1 +r/n)^(nt)
For the given numbers, we want to find t:
6000 = 3700(1 +.062/2)^(2t)
Dividing by 3700 and taking the logarithm, we get ...
6000/3700 = 1.031^(2t)
log(60/37) = 2t·log(1.031)
Dividing by the coefficient of t gives ...
t = log(60/37)/(2log(1.031)) ≈ 7.92 . . . . . years
It will take about 7 years 11 months for the investment to grow to $6000.
B should be the only correct answer.
