He has 14 coins what are either 10 dollars or 2 dollars, total amount is not greater than 95, how many 10 coins he has?
~~~~~~~~~~~~~~~~~~~~~~

Let x = # of 10-dollar coins. Then the number of 2-dollar coins is (14-x). The value expression is value = 10x + 2*(14-x) dollars. Your inequality is 10x + 2*(14-x) <= 95 ====> Simplify and solve it step by step: 10x + 28 - 2x <= 95, 8x <= 95 - 28 = 67. ====> x <= 8 Answer. Less than 9.

Solved.

----------------
Regarding the answer by @MathTherapy, I want to underline one more time:

The correct answer is "the number of 10-dollar coins is less than 9", which means N <= 8, BUT NOT NECESSARY N=8.
