If a clock ticks 4 times in the first minute and then 3 times each minute for the next 5 minutes, how many ticks will it have made in total?

Step-by-step solution

1. Ticks in the first minute: $4$.
2. Ticks per minute for the next 5 minutes: $3$.
3. Total ticks in those 5 minutes: $3\times 5=15$.
4. Add the first minute ticks: $4+15=19$.
5. State the total ticks: $19$.
