Eric sold his house through an agent who charged 8% commission on the selling price. If Eric received $117,760.00 after the sale, what was the selling price of the house?
- A. $130,000.00
- B. $128,000.00
- C. $125,000.00
- D. $120,000.00
Correct Answer: B. $128,000.00
Explanation
\(\frac{8}{100} \times x + 117,760 = x\)
x - \(\frac{8x}{100} = 117,760
\(\frac{92x}{100} = 117,760\)
x = \(\frac{117,760 \times 100}{92}\)
Selling price = N $128,000
