Answer:
after 30 days lease cost equal the purchase cost
Step-by-step explanation:
Data provided in the question:
Purchasing cost of the equipment = $12,000
operational costs = $400 per day
Lease amount for the equipment = $800 per day
Now,
Let the number of days after which lease cost equal the purchase cost be 'x'
therefore,
Total cost when purchased = $12,000 + $400x
Total cost when equipment is leased = $800x
therefore,
for equal costs
$12,000 + $400x = $800x
or
$800x - $400x = $12,000
or
$400x = $12,000
or
x = 30 days
hence,
after 30 days lease cost equal the purchase cost
