Answer:
The total number of hours = 35 hours.
Step-by-step explanation:
The annual fee of Calm Spa = $125
Per hour charge of Calm Spa = $10
Annual fee of Relax Spa = $230
Per hour charge of Relax Spa = $7
Now we have to find the number of hours for which both have same cost.
Let the number of hours = x
Thus, 125 + 10x = 230 + 7x
10x-7x = 230 – 125
3x = 105
x = 35
The total number of hours = 35 hours.
