Answer: The total cost of shipping various packages depends on their weights. Let's say a package weighs w pounds. The cost of shipping this package would be:
$5 per pound × w pounds + $3 signature fee = $5w + $3
So, if we know the weights of all the packages, we can calculate the total cost of shipping by adding up the costs of each package. For example, if we have three packages with weights of 2 pounds, 5 pounds, and 3 pounds respectively, the total cost of shipping would be:
($5 × 2) + $3 + ($5 × 5) + $3 + ($5 × 3) + $3 = $10 + $28 + $18 = $56
Therefore, the total cost of shipping various packages depends on the weights of the packages and can be calculated using the formula $5w + $3 for each package.
