Unformatted text preview: T , or: Marginal benefit = T B ∆ ∆ = a , where a is the slope of the line relating B to T . More generally, suppose that B is any positive function of time spent: B = b ( T ). In this case, the marginal benefit is given by the derivative of B with respect to T : Marginal benefit = T B d d = b ’ ( T ). When evaluated at time T , b ’ ( T ) is the slope of the line tangent to b ( T )....
