Let
x--------> the number of notebooks
y-------> the number of pens
we know that
[tex] 3.59x+1.49y\leq13 [/tex]
using a graph tool
see the attached figure
The solution is the shaded area
therefore
the answer is
the inequality that represents the situation is equal to [tex] 3.59x+1.49y\leq 13 [/tex]
