Answer: The average cost of a sofa is $350.
Step-by-step explanation:
Since we have given that
Cost of Advertised sofa = $400

![\dfrac{200\times 1+300\times 3}{4}\\\\=\dfrac{200+1200}{4}\\\\=\dfrac{1400}{4}\\\\=\$350](https://tex.z-dn.net/?f=%5Cdfrac%7B200%5Ctimes%201%2B300%5Ctimes%203%7D%7B4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B200%2B1200%7D%7B4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1400%7D%7B4%7D%5C%5C%5C%5C%3D%5C%24350)
Hence, the average cost of a sofa is $350.
