Here is the question:
I have posted a link there to this topic so the OP can see my work.
I need help with this problem !?
Sandy manages a ceramics shop and uses a 800°F kiln to fire ceramic greenware. After turning off her kiln, she must wait until its temperature gauge reaches 155°F before opening it and removing the ceramic pieces. If room temperature is 70°F and the gauge reads 700°F in 10 minutes, how long must she wait before opening the kiln? Assume the kiln cools according to Newton's Law of Cooling.
(Round you anwer to the nearest whole minute)
a) 512 mins B)94 mins c)369 mins D)146 mins
