Zara bought 2.4 pounds of grapes and a watermelon that cost $5.28. The total cost of the fruit was $7.32. Which describes a way to determine x, the price per pound for the grapes?
Solve for x in the equation 2.40
5.28 = 7.32
Divide 7.32 by 2.4 and then subtract 5.28 from the quotient.
Subtract 5.28 from 7.32 and then divide the difference by 2.4.
Solve for x in the equation 2.4 (2+5.28) = 7.32.
