PLEASE HELP!!!! 
The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and value of x, the cost of each cavity filling?

A. 4x + 89.95 = 628.35; x = $134.60

B. 4(89.95) + x = 628.35; x = $268.55

C. 4x + 89.95 = 628.35; x = $179.58

D. 4(89.95) + x = 628.35; x = $538.30

Respuesta :

Answer is A. 4x + 89.95 = 628.35; x = $134.60

4x + 89.95 = 628.35
4x = 628.35 - 89.98
4x =538.37
x = 538.37/4
x = 134.60

Starting off by labeling all of the her of the variables we have: Total: 628.35 X: 89.95 Clean up: sameness as x Now that we have everything we start the equation: 4x+89.95=628.35 Minus 89.95 on both sides. We are left with: 4x=538.84 Divide by 4: X=134.6 The answer to your question is A
