Answer:

She kayaked for 6 hours.

Step-by-step explanation:

If $10 is the initial fee, subtract $22 - $10 = $12.

If it charges $2 per hour, divide $12 by $2 which equals 6 hours.

Answer:

6 hours

Step-by-step explanation:

Cost = fee + charge per hour * number of hours

22 = 10 +2h

Subtract 10 from each side

22-10 = 10+2h-10

12 = 2h

Divide

12/2 = 2h/2

6 = h
