Answer:
$1
Step-by-step explanation:
The marginal cost is the extra costs that are to be incurred for producing an additional units
Provided that
Burritos = $5
Tacos = $3
So, the Total sales price = $8
Now this sales price is split evenly, that means it would be given the $4 to Jacob and the remaining 4 to Mason
So, the marginal cost would be
= $5 - $4
= $1
