Malik works at a hardware store for $12 per hour and as a lifeguard for $18 per hour. he needs to earn at least $280 per week, but he can work no more than 20 hours in total. write a system of inequalities that represents this situation. ! : )

The system of inequalities is equal to

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

-----> inequality A

-----> inequality B

Using a graphing tool

The solution is the shaded area

see the attached figure

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer is 8/21

hope this
