Answer:
Company 1 : Lease new jets.
Company 2 : Buy a color printer.
Explanation:
Lease and buy are both options available to a business for acquiring an equipment. Lease option is best suited to company 1 where the demand for private jet charter has increased in summer. The demand will not remain constant in other seasons so leasing the jets for summer season is best and less costly than buying them.
For company 2, it is better to purchase color printer rather than leasing it as the demand for volume print stays throughout the year and she wants to keep her cost at minimum. Leasing the printer will be an additional monthly expense while buying the printer is one time expense.
