Answer:

The system of inequalities is equal to

[tex]12x+18y\geq280[/tex]

[tex]x+y\leq 20[/tex]

Step-by-step explanation:

Let

x-----> the number of hours that Malik works at a hardware store

y-----> the number of hours that Malik works as a lifeguard

we know that

[tex]12x+18y\geq280[/tex] -----> inequality A

[tex]x+y\leq 20[/tex] -----> inequality B

Using a graphing tool

The solution is the shaded area
