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 $450,000. Ingrid allocated $75,000 of the purchase price to goodwill. Ingrids business reports its taxable income on a calendar-year basis. (Do not round intermediate calculations. Round your answers to the nearest whole dollar amount.)
