Answer 1

Answer:

Step-by-step explanation:

Sales man decides his sale price initially as marked price MP and gives a discount D%. Let us say the salesman's final decided selling price (excluding tax) is  P.

         Tax amount = Sales_tax% * P = x

If we say Sales_tax % is fixed as per laws, let us call it  C%.

 

        x = C% * P = P * C/100

       =>    P = 100 x /C

Retail Sale price =  RP = P + tax amount = 100 x /C + x

                      y = x (100/C+1) = (100+C) x / C

This is the linear relationship between the sales tax amount and the retail price.

     When x = $77.76, y = $972,

             => 100/C + 1 =  972/77.76  = 12.5

                =>    C  =  100 / 11.5 = 8.695  

 Hence y = 12.5 x   is the relationship between  sales tax and  retail price.

         with sales tax percentage being C = 8.695%

     sales tax = $92.34 = x

          =>  retail price = y = 12.5 * $92.34  = $ 1, 154.25
