Grapefruit 78 cents or .78 dollars ( amount per pound)
Rhubarb 4.99 dollars (amount per pound)
Cherries 11.98 dollars (total amount)
Because the money divided into the amount of pounds of fruit gets you the cost per pound(for the first two).
Then if your multiply the amount per pound multiplied by the pounds gets you the total cost (for the last one).
