Answer:
 Total combined weight of the fruit Everett bought is 358 ounce .
Explanation:
As given
Everett bought 6 pounds and 7 ounces of pomegranates, 5 pounds of melon and 15 ounces of lemon. 
As 1 pound = 16 ounce 
6 pound is convert into ounce .
6 pound = 6 × 16 
 = 96 ounce 
15 pound is convert into ounce .
15 pound = 15 × 16 
 = 240 ounce 
Thus 
Total combined weight of the fruit Everett bought = 96 ounce and 7 ounces of pomegranates + 240 ounce of melon and 15 ounces of lemon. 
 = 96 + 7 + 240 + 15 
 = 358 ounce 
Therefore total combined weight of the fruit Everett bought is 358 ounce .
