Answer:

Step-by-step explanation:
The given sequence is a geometric sequence.
We can find the common ratio using any two consecutive terms of the sequence.

The common ratio is 
4x + 89.95 = 628.35 <== ur equation
4x = 628.35 - 89.95
4x = 538.40
x = 538.40 / 4
x = 134.60 <== the cost for each cavity filling
3- What number, when multiplied by 4, equals -24?
