Calculating Total Pollutant Exposure

Question

The concentration of a pollutant is modeled by the function $$C(t) = 5 + 0.5t$$, where $$C(t)$$ is the concentration in parts per million (ppm) and $$t$$ is the time in hours. Calculate the total pollutant exposure in ppm·hours over the first 8 hours by evaluating the definite integral of $$C(t)$$ from $$t=0$$ to $$t=8$$.

Accepted Answer

56 ppm·hours

Answer

48 ppm·hours

Answer

72 ppm·hours

Answer

64 ppm·hours, a value likely arising from an overestimate of the area under the curve due to miscalculation of the integral.
