Tenfour has a twin brother Bubba Goodbuddy. Sometimes
one of the brothers will sell an opportunity to another. If they
both have the same utility function

u(X) =sqrt((x-(-5000))/(5000-(-5000))

CME(u)=-5000+(5000-(-5000)*u^{2}

What is the least Tenfour would accept to sell his opportunity?

What is the most Bubba would pay to acquire this opportunity?

Suppose, instead, they both thad an exponential utility
function,

u(X)=1.3069*(1-exp{-0.000144879*[X-(-5000)]})

CME(u)=-ln({1.3069-u}/1.3069)/0.000144879+(-5000)

Using this utility function,

What is the least Tenfour would accept to sell his opportunity?

What is the most Bubba would pay to acquire this opportunity?
