Question

Marly has to get some cavities filled at the dentist. The dentist charges a fee of $35 plus $43 per cavity. If Marly ends up having a bill of $164 and c represents the number of cavities, which of the following equations could be used to find how many cavities Marly had filled?

A. 35 = 164 + 43c

B. 164 = 35 - 43c C. 164 = 35c + 43 D. 35 + 43c = 164

Answer 1

35+43c=164 is one expression that can be used because the fee is 35 then plus 43 per cavity

Answer 2

D. 35+43c=164. Because it says $35 plus $43 per cavity and it would equal 164
