Explanation:
Let's represent apples and oranges with the variables:
• x: amount of apples
,• y: amount of oranges
The sum of the amount of oranges and apples must be no more than 10:
[tex]x+y\le10[/tex]If each apple cost $2, then x apples cost 2x. Also, if each orange cost $4, then y oranges cost 4y. The sum of these costs must be less than 22:
[tex]2x+4y<22[/tex]Answers:
a. The system is:
[tex]\begin{cases}x+y\le10 \\ 2x+4y<22\end{cases}[/tex]b. The graph:
In blue it's the graph of the first inequality and in green is the graph of the second inequality.
