Final answer:
The formula for the chicken's temperature over time is H(t) = -18 + (3%)(t).
Step-by-step explanation:
To find a formula for the chicken's temperature, we need to consider the rate at which it is warming up in the refrigerator. The difference between the temperature of the refrigerator (3°C) and the chicken's temperature initially (-18°C) is decreasing over time at a rate of 3% per minute.
So, the chicken's temperature, H(t), can be represented by the equation:
H(t) = -18 + (3%)(t)
Where t is the time in minutes after the chicken was removed from the freezer.
