Answer:
B. $3
Explanation:
A single 6-pound package is approximately $5 shipping fee.
A 2-pound package is approximately $3.50 shipping fee.
A 4-pound package is approximately $4.50 shipping fee.
The question stated, "What is the approximate difference (this means we are most likely subtracting) in cost of shipping a 2-pound and a 4 pound package(the and means we are adding both 4-pound and 2-pound together) opposed to a single 6-pound package?"
As calculated above, we should add the 2-pound package and the 4-pound package together.
3.5 + 4.5 = 8
One single 6-pound package is $5, so we need to subtract the 8 with the 5.
8 - 5 = 3
