Solve the problem.Sandy manages a ceramics shop and uses a 
kiln to fire ceramic greenware. After turning off her kiln, she must wait until its temperature gauge reaches 
before opening it and removing the ceramic pieces. If room temperature is 
and the gauge reads 
in 10 minutes, how long must she wait before opening the kiln? Assume the kiln
cools according to Newton's Law of Cooling: U = T + (Uo - T)ekt.(Round your answer to the nearest whole minute.) A. -236 minutes B. 77 minutes C. 166 minutes D. -356 minutes
