Answer:
The combined weight of red and green grapes in total= 7.625 pounds.
Step-by-step explanation:
The amount of red grapes purchased = 3.5 pounds
The amount of green grapes purchased = 4 pounds and 2 ounces
Now, 1 ounce = 0.0625 pounds
So, 2 ounces = 2 x 0.0625 p = 0.125 pound
So, the amount of green grapes purchased = 4 pounds + 0.125 pounds
= 4. 125 pounds
Now, the combined weight of grapes = weight of ( red + green) grapes
= 3.5 pounds + 4. 125 pounds
=7.625 pounds
Hence, the combined weight of the red and green grapes she bought in total is 7.625 pounds.
