The formula to calculate the Delivery Tip (DT) is:
\[ DT = (B \cdot r) + E \]
Where:
A Delivery Driver Tip is an additional amount of money given to a delivery driver as a token of appreciation for their service. This is usually given on top of the payment for the goods or services delivered. The tip serves as a reward for the driver’s effort, especially if they delivered the items promptly, professionally, and in good condition. The amount of the tip can vary, but it is often based on a percentage of the total bill, the distance traveled, or the complexity of the delivery.
Let's assume the following values:
Using the formula:
\[ DT = (50 \cdot 0.15) + 5 = 7.50 + 5 = 12.50 \]
The Delivery Tip (DT) is $12.50.
