To find the number of visits (let's call it \( x \)) at which the costs of the two plans are equal, we need to set up the equations for both options.
-
The first option (paying per visit) costs: \[ \text{Cost}_1 = 10x \] where \( x \) is the number of visits.
-
The second option (paying a monthly fee plus per visit) costs: \[ \text{Cost}_2 = 32 + 6x \]
We want to find \( x \) when the costs are equal, so we set the two equations equal to each other: \[ 10x = 32 + 6x \]
Now, we can solve for \( x \). First, subtract \( 6x \) from both sides: \[ 10x - 6x = 32 \] \[ 4x = 32 \]
Next, divide both sides by 4: \[ x = \frac{32}{4} = 8 \]
Thus, the number of visits at which the costs of the two plans are equal is \( x = 8 \).
The correct response is:
- 10x = 32 + 6x; x = 8
