8_murik_8 [283]

Answer:

C. No, it will increase cost by $100.

Explanation:

Z Corp. can make three individual deliveries to three different customers at a cost of $500 each

Given that:

Cost of shipment = $1300

Cost of each delivery = $500

Stop of charge = $100 per stop

Total cost if for individual delivery to three different customers = 3($500) = $1500

Since they are three different customers, the total stop charge = 3($100)

cost for consolidating them into one shipment= $1300 + 3($100) = $1300 + $300 = $1600

Therefore there is an increase in cost of $1600 - $1500 = $100
