To find out how many hours a tiger will sleep in 7 weeks, we first calculate the total number of hours in 7 weeks.
There are 7 days in a week, so:
\[ 7 \text{ weeks} \times 7 \text{ days/week} = 49 \text{ days} \]
Now, let's calculate the amount of sleep:
If a tiger sleeps between 18 to 20 hours a day, we find the total sleep over 49 days:
For the lower estimate (18 hours a day): \[ 49 \text{ days} \times 18 \text{ hours/day} = 882 \text{ hours} \]
For the upper estimate (20 hours a day): \[ 49 \text{ days} \times 20 \text{ hours/day} = 980 \text{ hours} \]
Therefore, a tiger will sleep between 882 to 980 hours in 7 weeks.
The correct response is: 882 to 980 hours.
