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.

Answer:

Sam

30

Step-by-step explanation:

Sam made a mistake when he said 10^2 -20. The steps should have been:

2n^2-20=2(5)^2-20\\2(25)-20\\50-20=30

You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.
