kayla recieves a bill of $754 for a new sofa. The bill includes a 6.2% tax on the sofa's selling price and a $26 delivery fee. Which equation could be used to find the selling price (x) of the sofa?

SP = Bill amount - tax - delivery charge

Step-by-step explanation:

Selling price of the sofa = Price of the sofa + tax + delivery fee

Now we have to find the SP of the sofa as,

First we have to take off the delivery charge = $ 754 - $ 26 = $ 728

For this amount we have to find the tax as,

728 * 6.2 / 100 = 45.136

So we have to subtract this tax from the value,

728 - 45.136 = $ 682.9

Selling price (x) of the sofa = $ 682.9
