Let x be the number of visits.
For the first option:
Cost = $10x
For the second option:
Cost = $32 + $6x
We want to find when the two costs are equal, so we set up the equation:
$10x = $32 + $6x
Subtract $6x from both sides:
$4x = $32
Divide by $4:
x = 8
It would take 8 visits for the cost of the two options to be equal.
