Patricia had less than nine dollars 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. 1 pound of tomatoes cost $2.40 and 1 pound of potatoes cost $2.20 .
part a: write an inequality to show how many pounds of potatoes, x, patrica can buy.
part b: solve the inequality from part a to find how many pounds of potatoes patricia can buy.

  Part A:  2.40 +2.20x ≤ 9.00

  Part B:  x ≤ 3; Patricia can buy 3 pounds of potatoes or less

Step-by-step explanation:

Part A. The total amount Patricia can spend at the grocery store will be at most $9.00. This amount includes the amount spent on tomatoes ($2.40) and the amount spent on potatoes ($2.20x). The amount spent on potatoes is $2.20 for each of the x pounds she want to buy, so will be the product of 2.20 and x.

The inequality is ...

  2.40 + 2.20x ≤ 9.00 . . . . . the total of Patricia's purchases is at most $9.

__

Part B. The inequality is solved in basically the same way it would be solved if it were an equation.

  2.20x ≤ 6.60 . . . . . subtract 2.40

  x ≤ 3 . . . . . . . . . . . . divide by 2.20. (This number is positive, so we keep the sense of the comparison as it is.)

Patricia can buy at most 3 pounds of potatoes.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

x = 23.78
