Answer:the truck load of fruit weigh 440 pounces
Explanation:
Let the total weight of the truck load of fruit weigh x pounds.
The truck carries apples, grapes, and blackberries in the ratio of 4:3:4
The total ratio is the sum of the proportions of apples, grapes, and blackberries. It becomes 4+3+4 = 11
if the apples weigh 160 pounds, it means that
4/11 × x = 160
4x/11 = 160
4x = 160×11 = 1760
x = 1760/4
x = 440
