Zina [12379]

Answer:

Step-by-step explanation:

Annual gross salary = $28000

Income tax = 20% applicable to earnings exceeding $15000

Thus, she has a taxable amount of $5000

Rent loan equals $140 monthly = $140 * 12= $1680 per year

Fair Y = 100/590 * 100 = 16.9%

This indicates that fair Y had a higher percentage of goats compared to fair X.
