For computing the marginal social benefit of the first plant the relevant information is provided as per the question below:-

Robin first plant benefit per day = $47

Greg first plant benefit per day = $41

Ray first plant benefit per day = $31

Marginal social benefit of the first plant = Robin first plant benefit per day + Greg first plant benefit per day + Ray first plant benefit per day

= $47 + $41 + $31

= $119

Therefore for computing the marginal social benefit of the first plant we simply added all the three employees first plant benefit per day.
