Correct Answer: B

Rationale

Choice B is correct. Let x be the original price, in dollars, of the Glenview Street property. After the 40% discount, the price of the property became $0 point 6 x$ dollars, and after the additional 20% off the discounted price, the price of the property became $0 point 8 times 0 point 6 x$ . Thus, in terms of the original price of the property, x, the purchase price of the property is $0 point 4 8 x$ . It follows that $0 point 4 8 x equals 140,000$ . Solving this equation for x gives $x equals 291,666 point 6, with the 6 repeating after the decimal point$ . Therefore, of the given choices, $291,700 best approximates the original price of the Glenview Street property.

Choice A is incorrect because it is the result of dividing the purchase price of the property by 0.4, as though the purchase price were 40% of the original price. Choice C is incorrect because it is the closest to dividing the purchase price of the property by 0.6, as though the purchase price were 60% of the original price. Choice D is incorrect because it is the result of dividing the purchase price of the property by 0.8, as though the purchase price were 80% of the original price.
