What is the cost of 50.5 board feet of lumber priced at $1.15 per board foot?

• A. $45.15
• B. $58.05
• C. $60.50
• D. $50.00

Answer: (B)

To determine the total cost of the lumber, you multiply the amount of lumber in board feet by the price per board foot. In this case, you have 50.5 board feet of lumber and it costs $1.15 per board foot.

The calculation is as follows:

Total Cost = Number of Board Feet × Price Per Board Foot

Total Cost = 50.5 board feet × $1.15/board foot

Performing the multiplication:

Total Cost = 50.5 × 1.15 = 58.075

When rounded to two decimal places, this total is $58.08, which aligns with one of the answer choices given in the question. Generally, prices are represented in two decimal places, so rounding $58.075 to $58.08, rather than simply truncating, demonstrates an accurate understanding of financial calculations involving currency.

Thus, the total cost for 50.5 board feet of lumber at the specified price is correctly represented by the choice related to $58.05.
