Answer:
$380
Step-by-step explanation:
Ziva's total cost of farming is composed of two different costs: explicit and implicit costs.
Explicit cost is an out-of-pocket cost that a person incurs to carry out a particular business activity. It is sort of, a business-related expense for which the business pays. In Ziva's case, it is $130, the cost of the seeds
Implicit costs are opportunity costs. An opportunity cost refers the benefits an individual, investor or business misses out on when opting for one alternative in preference of another. In our case, it amounts to $250($25*10 hours)
Thus, Ziva's cost of farming
= $130 +( $25*10) = $130 +$250 = $380
