Question

Mark buys a wooden board that is 7 1/2 feet long. The cost of the board is $0.50 per foot, including tax. What is the total cost, in dollars, of Mark's board?

Answer 1

Answer:

Total cost of Mark's board is $3.75.

Step-by-step explanation:

We are given the following in the question:

Length of wooden board =

$=7\dfrac{1}{2}\text{ foot}$

Unit cost of board = $0.50 per foot

Total cost of board =

$=\text{Length of board}\times \text{Unit cost of board}\\\\=7\dfrac{1}{2}\times 0.50\\\\=\dfrac{15}{2}\times \dfrac{1}{2}\\\\=\dfrac{15}{4} = 3.75$

Thus, total cost of Mark's board is $3.75.
