Answer 1

The fixed charge for each delivery is not given in the question. For part (b), let's assume a fixed charge of $10 per delivery. The difference between the two delivery costs is 20 miles.

Step-by-step explanation:

The fixed charge for each delivery is not given in the question, so we cannot determine the exact amount without more information.

For part (b), let's assign variables to the distances of the two deliveries. Let x represent the distance of one delivery, and x + 20 represent the distance of the other delivery. Let's assume the fixed charge is $10 for each delivery.

Then, the delivery costs can be calculated as follows:

Delivery 1 cost = Fixed charge + distance charge = $10 + x

Delivery 2 cost = Fixed charge + distance charge = $10 + (x + 20)

The difference between the two delivery costs will be:

Delivery 2 cost - Delivery 1 cost = ($10 + (x + 20)) - ($10 + x)

Simplifying the expression, we get:

Delivery 2 cost - Delivery 1 cost = x + 20 - x = 20 miles.
