Answer:
a large percentage of the total cost
Step-by-step explanation:
When a product has a high value to weight ratio it means it is expensive and the weight is light. For products with low value to cash ratio they are cheap but have large weight.
Low value to weight ratio goods are more expensive to transport and they do not make up the high transportation cost because they are also cheap.
In this scenario Sweet Stuff Sugar Source ships low value to weight goods all over the world. So their transportation cost will be high and it will make up a large percentage of total cost.
