Final answer:
A good estimate of the amount of taxes Karina is going to pay for her $375,000 house is $4,500.
Step-by-step explanation:
To estimate the amount of taxes Karina is going to pay for her $375,000 house, we can use the ratio of the tax amount to the house price from her uncle's situation. Her uncle's house is worth $680,000 and he pays $8,160 in taxes. We can set up a proportion to find Karina's estimated taxes:
(8,160 / 680,000) = (x / 375,000)
Cross multiplying and solving for x, we get:
x = (8,160 * 375,000) / 680,000 ≈ $4,500
Therefore, a good estimate of the amount of taxes Karina is going to pay is $4,500.
