Answer:

The system of linear inequalities is equal to

[tex]4x+10y\leq 100[/tex]

[tex]y\geq 5[/tex]

Step-by-step explanation:

Let

x-----> the number of bags of salt

y-----> the number of bags of sand

we know that

[tex]4x+10y\leq 100[/tex] -----> inequality A

[tex]y\geq 5[/tex] ------> inequality B

Using a graphing tool

see the attached figure

The solution of the system of inequalities is the triangular shaded area
