Back question 323 of 383 Next

Explanation

Choice B is correct. It's given that 140 is p% greater than 10 . It follows that 140=10+p10010, which is equivalent to 140=10+10100p, or 140=10+0.1p. Subtracting 10 from each side of this equation yields 130=0.1p. 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.
