Bob loves to eat blue jelly beans. He gets 50 units of utility for the first jelly bean, 40 units of utility for the second, 30 units of utility for the third, 20 units of utility for the fourth, and an additional 10 units of utility for the fifth. For the first jelly bean, the marginal utility is 50, and the total utility for eating five jelly beans is 150.  Utility is the benefit derived from consuming a product or using a service. Bob gets 50 units of utility for consuming the first jelly bean. His utility is 50. The total utility is the summation of the satisfaction Bob derived from eating the five jelly beans.

                   = 150 units of utility
