Which shows the correct equation and value of x, the cost of each cavity filling? 4 x 89. 95 = 628. 35; x = 134 dollars and 60 cents 4 (89. 95) x = 628. 35; x = 268 dollars and 55 cents 4 x 89. 95 = 628. 35; x = 179 dollars and 58 cents 4 (89. 95) x = 628. 35; x = 538 dollars and 40 cents.

An equation is considered as assertation of equality between two expressions containing variables. Equations are attempts to discover systematic answers.

Cost of each cavity filling

Correct option is A.

Given Information:

  • Total cost=$628.35
  • Flat fee=$89.95
  • Cavities filled=4

The trip to the dentist had a flat fee plus 4 cavities for a total cost of 628.35.

=fee + 4 * cost of cavity = 628.35

=Let x = the cost of each cavity

=89.95 + 4x =628.35

Subtract 89.95 from each side,

89.95-89.95 + 4x =628.35-89.95

4x =538.40

Divide each side by 4

4x/4 =538.40/4

x =134.60
