Question 784478: To treat arrhythmia (irregular heartbeat), a drug is fed intravenously into the bloodstream. Suppose that the concentration c of the drug after t hours is given by
c = 3.5t/(t + 1)
mg/L. If the minimum therapeutic level is 1.5 mg/L, determine when this level is exceeded. (Give your answer as an inequality in terms of t.)

3.5t/(t+1)>1.5
3.5t>1.5(t+1)
3.5t>1.5t+1.5
2t>1.5
t>.75 hr
