Question

Marley has to get some cavities filled at the dentist. The dentist charges a fee of 35 plus 43 per cavity . If Marley ends up with a bill 164 dollars, how many cavities did Marley have filled

Answer 1

Fee of Dentist=$30

Per Cavity=$43

Let Marley Have Total X cavity.

Then Total Cost=$43x

Total Bill=$164.

A/Q

35+43x=164

43x=164-35

43x=129

x=129/43

x=3

$\boxed{\mathbf{Marley \:Have\:Total=3\:Cavity}}$
