The answer is 17/5. First you multiply 5*3=15 then you add 2 which your answer is 17/5.
For this case, the first thing we must do is define variables.
We have then:
x: number of pens
y: number of pencils
We now write the system of inequations:

The solution to the system of inequations is given by the shaded region.
