We need to find the number of hours does the quality control facility operate each day.
Rewrite the given function it factored form.


Taking out the common factors from each parenthesis.



The factored form of given function is c(t)=-(t-10)(t+2).
Equate the function equal to 0 to find the x-intercept.



Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.
Therefore the quality control facility operates for 10 hours each day.
