140 is p % greater than 10 . What is the value of p ?

Question

Accepted Answer

Choice B is correct. It's given that 140 is p % greater than 10 . It follows that 140 = 10 + p 100 10 , which is equivalent to 140 = 10 + 10 100 p , or 140 = 10 + 0.1 p . Subtracting 10 from each side of this equation yields 130 = 0.1 p . Dividing each side of this equation by 0.1 yields 1,300 = p , or p = 1,300 . Choice A is incorrect. This would be the value of p if 140 were p % of 10 , not p % greater than 10 . Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
