A girl scout troops uses 14 flashlight batteries on a three-night camping trip. If they are planning a seven-night trip, about how many batteries should they bring?
To figure out how many batteries the girl scout troop should bring for a seven-night trip, we can use a proportion based on the number of nights they went on their previous trip.
14 batteries / 3 nights = x batteries / 7 nights
Cross-multiplying, we get:
3 * x = 14 * 7
Simplifying, we find:
3x = 98
Dividing both sides by 3, we conclude:
x = 98 / 3
Performing the division, we determine that they should bring approximately 32.67 batteries. Since they cannot bring a fraction of a battery, they should bring 33 batteries.
