<u>Answer-</u>
![\boxed{\boxed{2.50x+4y\leq 20}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7B2.50x%2B4y%5Cleq%2020%7D%7D)
<u>Solution-</u>
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
Taking a point as origin (0, 0) and then putting it in the equation,
![\Rightarrow 2.5(0)+4(0)\leq 20\\\\\Rightarrow 0\leq 20](https://tex.z-dn.net/?f=%5CRightarrow%202.5%280%29%2B4%280%29%5Cleq%2020%5C%5C%5C%5C%5CRightarrow%200%5Cleq%2020)
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)
