Question

Given this function of 2 variables:
\[C= f(x,t)=te ^{-t(4-x)}\] and the and f(2, 0.5)



And if C = concentration of a drug in milligrams of a drug in the blood as a function of x, the amount, in mg, of the drug given and t, the time in hours since the injection.

Shouldn't the answer be .5e ? which is ~1.359mg/L?

what am I doing wrong?
