Marsha is buying salt and sand for defrosting her driveway. the salt cost $4 per bag, and the sand cost $10 per bag. she wants to buy at least 5 bags of sand and can spend no more than $100. write a system of linear inequalities to model the situation

The system of linear inequalities is equal to

Step-by-step explanation:

Let

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

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

we know that

-----> inequality A

------> inequality B

Using a graphing tool

see the attached figure

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