<span>Average profit from the sale of 1 piece of furniture = 3x + 1
Average number of pieces of furniture that can be made using current supply of raw materials = 3x - 1.
Therefore,
Average profit of total furniture = Average profit X Average total of furniture sold
= (3x + 1) X (3x - 1)
= 9x^2 - 1</span>

Answer: (7x + 1)(x + 7)
Step-by-step explanation:

Answer: 0.72/20; 1.98/20; 17.3/20
0.036 * 10/10 = 0.36/10 * 2/2 = 0.72/20
0.099 * 10/10 = 0.99/10 * 2/2 = 1.98/20
0.865 * 10/10 = 8.65/10 * 2/2 = 17.3/20
