A clock ticks 2 times in each of the first 3 minutes, then 3 times each of the next 2 minutes, and finally 5 times each of the following 2 minutes. How many ticks has it made in total?

Step-by-step solution

1. Count ticks for the first 3 minutes: $2\times 3=6$ ticks.
2. Count ticks for the next 2 minutes: $3\times 2=6$ ticks.
3. Count ticks for the last 2 minutes: $5\times 2=10$ ticks.
4. Add all parts: $6+6+10=22$ ticks.
