Final answer:
To calculate the total cost of a customized door, multiply the hourly fee by the number of hours worked and add it to the base price. A door with a $500 base price and $75 hourly fee for a 4-hour customization would cost $800 in total.
Step-by-step explanation:
The question asks about calculating the total cost of a customized door given a base price and an hourly fee for customization. The door is 500 base price and there is a no 75 hourly fee. To find the total cost, you would calculate the cost of customization for the time spent and add it to the base price.
Since the customization takes 4 hours and the hourly fee is 75, you would calculate the customization cost as:
4 hours x $75/hour = $300
Adding the customization cost to the base price of the door:
$500 (base price) + $300 (customization fee) = $800
Therefore, the cost of a door that you customized for 4 hours would be $800.
