Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $1
Olenka [21]

Answer:

\$16,826,000.

Step-by-step explanation:

We have been given that Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $15,342,000 the third quarter, and a loss of $48,037,000 for the fourth quarter.

To find the net profit for year, we will subtract the loss in the 4th quarter from the sum of profit in 3 quarters as:

\text{Net profit for the year}=\$28,951,000+\$20,570,000+\$15,342,000-\$48,037,000

\text{Net profit for the year}=\$64,863,000-\$48,037,000

\text{Net profit for the year}=\$16,826,000

Therefore, the net profit for the year was \$16,826,000.
