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?
4x+89.95 - 628.35; X = $134.60
4(89.95) + X = 628 35
X = $268.55
4x+89.95-628.35; X = $179.58
4(89.95)+ X 628 35:
- $538 40
