Suppose that the polynomial function a(x) = - 0.0082x2 + 0.06x approximates a person's blood-alcohol level x hours after drinking 5 ounces of 80-proof whiskey. what is the person's blood-alcohol level after 3 hours?

Given that the blood-acohol level at time x is given by A(x)=-0.0082x²+0.06x. The blood-alcohol after 3 hours for a person who has drunk 5 ounces pf 80-proof whiskey will be:
A(3)=-0.0082(3)²+0.06(3)
A(3)=-0.0738+0.18
A(3)=0.1062
the amount of blood-alcohol after 3 hours will be 0.1062

Ithink the answer is c just trying to others
