The average cost of a sofa is $350.

Step-by-step explanation:

Since we have given that

Cost of Advertised sofa = $400

Cost of more expensive sofa = $600

So, the average cost of a sofa is given by

$\dfrac{200\times 1+300\times 3}{4}\\\\=\dfrac{200+1200}{4}\\\\=\dfrac{1400}{4}\\\\=\$350$

Hence, the average cost of a sofa is $350.
