Problem B

Jafarâ€™s New Floor

Jafar is laying new hardwood flooring in his rectangular living room, which has an area of \(66~\text{m}^2\). Each box of flooring has \(8\) identical wooden planks, and each plank has an area of \(0.2~\text{m}^2\).

Assuming that there is no waste, how many planks will he need to cover the floor of his living room?

If Jafar wants to buy an extra \(10\%\) for waste, how many boxes of flooring does he need to buy?

If each box costs \(\$74.50\) and sales tax is \(15\%\), what will be the total cost of the flooring in part (b)?
