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?

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
