you can spend at most $20 on tomatoes and red peppers for a soup. tomatoes cost $2.50 per pound and red peppers cost $4 per pound. write and graph an inequality that represents the amounts of tomatoes and red peppers you can buy.

Answer-
[tex]\boxed{\boxed{2.50x+4y\leq 20}}[/tex]
Solution-
The total money that you have or maximum amount that you can spend = $20
Let's assume,
x = Number of tomatoes bought
y = Number of red peppers bought
Price of tomatoes per pound = $2.50
Price of red peppers per pound = $4
Hence,
Total cost of tomatoes = $2.5x
Total cost of red peppers = $4y
As you can spend at most (any amount less than or equal to) $20, so
[tex]2.5x+4y\leq 20[/tex]
Taking a point as origin (0, 0) and then putting it in the equation,
[tex]\Rightarrow 2.5(0)+4(0)\leq 20\\\\\Rightarrow 0\leq 20[/tex]
As this satisfies, so the shaded region will be towards that point i.e origin
From the graph, the two solutions that are on the boundary line are (8, 0), (5, 0)
