To calculate the cost of deck repair:
\[ DR = (A \cdot m) + (B \cdot n) + C \]
Where:
Deck repair refers to the process of fixing or restoring a deck to its original or functional state. This could involve a range of activities such as replacing damaged or rotten wood, fixing loose or broken boards, repairing cracks, re-staining or painting, and overall maintenance to ensure the deck is safe and aesthetically pleasing.
Let's assume the following values:
Using the formula:
\[ DR = (200 \cdot 5) + (10 \cdot 20) + 100 = 1400 \]
The total cost of deck repair is $1400.
