(2) The charge for the last 3 minutes of the call was $0.01 less than half the total cost of the call Total Cost = 5.99 + 1.99*(x-2) 1) Total cost = 11.96. We can find out the value of x easily by substituting total cost in the above equation. hence, Sufficient. 2) Last 2 minutes charge = (total/2)-0.1. We don't know the total cost. Also, even if we know the total cost, still we cannot find out the how many minutes were there before the last 3 minutes. hence, insufficient.

Hi Bunuel,

I got answer D.
But i have a question.

Statement 2 says last 3 minutes of the call, in which case, x >= 5. Because if x = 4, then last 2 minutes will be charged at 1.99$, however last 3rd minute cannot be calculated as it would be part of first 2 minutes charged 5.99 and can't be broken down. Is my answering correct? Please help. thanks Re: A call to Rosie’s Psychic Hotline costs$5.99 for the first 2 minutes   [#permalink] 13 Mar 2018, 02:54
