Re: If (5x + 11) is a positive integer, for how many integer values of x [#permalink]
road740 wrote:
Calculate 5x + 11 < 300

--> x < 57,8

and since x is an int, x<57.

You could be tempted to click on (B); however, we want to know for how many values the positive expression (5x + 11) will be < 300.

x could be also 0,-1 and -2, since all these values still make a positive expression of (5x + 11) and are less than 300.


So: Answer is (E) 60 values.
Best regards :)


Dear road740,

Your soln. is correct but if I may point out just a small oversight.

Note \(x \leq 57 \) not just \(x<57\) we need to include \(57. \)
