Patricia had less than $9 to spend when she went to the grocery store. She bought 1 pound of tomatoes and wanted to spend the rest of her money on potatoes. One pound of tomatoes costs $2.40, and one pound of potatoes costs $2.20. Write an inequality to show how many pounds of potatoes, X, Patricia can buy.

Answer:2.40 + 2.20x < 9, Where x ≥ 0,Step-by-step explanation:Here x represents the number of pounds of potatoes bought by Patricia,Since, one pound of potatoes costs $2.20,⇒ x pounds of potatoes costs 2.20x dollars,Now, except this she bought 1 pound of tomatoes which costs $2.40 per pounds,Thus, her total spending,S = 2.40 + 2.20xIt is given that she had less than $9 to spend,⇒ S < 9⇒ 2.40 + 2.20x < 9Which is the required inequality.Note : Number of pounds can not be negative,⇒ x ≥ 0
