John receives a marginal benefit of $80 from one missile. nick receives a marginal benefit of $50 from one missile. christina receives a marginal benefit of $65 from one missile. john, nick, and christina are the only people in the economy. what is the economy's marginal social benefit from one missile? $65 $195 $50 $80

Economy's marginal social benefit=$65

Explanation:

The economy's marginal social benefit can be calculated by getting the average of the individual marginal benefit.

This can be expressed as;

Economy's marginal social benefit=Sum of individual marginal benefit/Total number of individual's

where;

Sum of individual marginal benefit=John's marginal benefit+Nick's marginal benefit+Christina's marginal benefit=(80+50+65)=$195

Total number of individuals=3

replacing;

Economy's marginal social benefit=195/3=65

Economy's marginal social benefit=$65
