After several profitable years running her business, Ingrid

decided to acquire the assets of a small competing

business. On May $1$ of year $1,$ Ingrid acquired the

competing business for $$432,000.$ Ingrid allocated

$$72,000$ of the purchase price to goodwill. Ingrid's

business reports its taxable income on a calendar$-$year

basis.

Note: Do not round intermediate calculations. Round

your answers to the nearest whole dollar amount.

b$.$ In lieu of the original facts, assume that Ingrid purchased only a phone

list with a useful life of five years for $$21,000.$ How much amortization

expense on the phone list can Ingrid deduct in year $1,$ year $2,$ and year $3?$

Please explain how you got the answer! I$\text{'}$m trying to learn, this is a resource.
