Final answer:
The buyer should offer $110,000 for the house.
Step-by-step explanation:
To calculate how much the buyer should offer for the house, we need to determine the value of the house after accounting for the repair and painting costs. The house is 1,800 square feet, and comparable houses sell for $65 per square foot. So, the initial value of the house is 1,800 * $65 = $117,000.
The repair cost is $2,200 and the painting cost is $4,800, totaling $7,000. To find the final offer price, we subtract the cost of repairs from the initial value: $117,000 - $7,000 = $110,000.
Therefore, the buyer should offer $110,000 for this house, which is option a.
