Answer:
The boxes are worth $1800
Explanation:
Step 1: Convert the 8 ounces and add it to the 4 pounds:
1 pounds equals 16 ounces.
Thus, we can determine how many pounds is 8 ounces by dividing 8 by 16:
Pounds = 8/16
Pounds = 0.5
Thus, 8 ounces equals 0.5 pounds.
Now we can add 0.5 to 4 to determine the weight of the boxes in pounds only:
Weight = 4 + 0.5
Weight = 4.5
Thus, the two boxes weight 4.5 pounds.
Step 2: Multiply 4.5 and $400:
Since each pound is worth $400, we can determine the worth of the boxes by multiplying 4.5 by 400:
Worth = 4.5 * 400
Worth = 1800
Thus, the boxes are worth $1800.
