To find out how many visits would make the cost of both plans the same, we can set up an equation.
Let \( x \) be the number of visits.
For the first plan:
- Cost = \( 10x \)
For the second plan:
- Cost = \( 30 + 4x \)
Now, we can set the two costs equal to each other:
\[ 10x = 30 + 4x \]
Next, we can solve for \( x \):
- Subtract \( 4x \) from both sides:
\[ 10x - 4x = 30 \]
\[ 6x = 30 \]
- Divide both sides by 6:
\[ x = \frac{30}{6} = 5 \]
Therefore, the plans would cost the same at 5 visits.
