To find the number of visits per month at which the two plans cost the same, we can set up an equation based on the costs of each plan.
-
Cost of the first plan (pay-as-you-go):
- The cost is $8 per visit.
- If \( x \) is the number of visits, the total cost for this plan can be expressed as: \[ \text{Cost}_{\text{plan 1}} = 8x \]
-
Cost of the second plan (monthly subscription):
- The cost is $40 per month plus $2 per visit.
- The total cost for this plan can be expressed as: \[ \text{Cost}_{\text{plan 2}} = 40 + 2x \]
Now, we set the two expressions equal to each other to find the number of visits \( x \) at which both plans cost the same: \[ 8x = 40 + 2x \]
Next, we can solve this equation for \( x \):
-
Subtract \( 2x \) from both sides: \[ 8x - 2x = 40 \] \[ 6x = 40 \]
-
Divide both sides by 6: \[ x = \frac{40}{6} = \frac{20}{3} \approx 6.67 \]
Thus, the number of visits per month that it would take for the two plans to be equal is approximately 6.67 visits. Since you typically can't have a fraction of a visit, it means that for less than about 6.67 visits, Plan 1 would be cheaper, and for more than about 6.67 visits, Plan 2 would be cheaper.
