Add Overheads and Finalize Base Price

What happens here

After determining both material and labor costs, additional factors must be considered. If the existing ground is soft or spongy, an additional layer of sand may be required as a stable base, which will increase the material cost. Combining the previously calculated material cost ($2.25/L.f.) and labor cost ($4.33/L.f.) gives a subtotal of $6.58 per linear foot. To ensure a profitable bid, an additional 10% is added for profit and overhead. This adds $0.67 (10% of $6.58), bringing the technical cost to $7.42 per linear foot. For the sake of simplicity and to provide clear, easy-to-understand options for customers, this is rounded up to $7.50 per linear foot.

Goal: Establish a final, profitable price per linear foot that includes all direct costs and a margin for profit/overhead.
