Hey there!
The answer is the second one : Solve x in the equation 2.4x - 5.28 = 7.32.
You multiply 5.28 from both sides leaving the equation to be 2.4x = 2.04
Then you divide both sides by 2.4 to get x alone.
You should get x = 0.85
Which means 0.85 is how much the price per pound of the grapes are.
Hope this helps !
