The total cost is the sum of the original and the sales tax which is presented in the equation, 
                                            C = p + rp
Substituting the known values to the equation, 
                                   C = $52.99 + (0.08)($52.99)
                                          C = $57.23
Thus, the answer is the fourth among the choices.

Answer:

the answer is $57.23

Step-by-step explanation:

hope thise helps

c = p + r*p

c = 52.99 + (0.08)*(52.99)

c = 52.99 + 4.2392

c = 57.2292

So the total cost of the shoes is $57.23.

The pair of shoes costs $52.99, so p = 52.99.

The state sales tax is 8%, which can be changed to decimal form by dividing by 100: 8/100 = 0.08. So r = 0.08.

Now you can plug both of these values into the formula to find the total cost of the shoes (c):

 

c = p + r*p

c = 52.99 + (0.08)*(52.99)

c = 52.99 + 4.2392

c = 57.2292

So the total cost of the shoes is $57.23.
