Name POW Comp-9 Due Date Brooke, Molly, and their mother and father went backpacking in Southlake National Park. On the first and second days each hiker had a serving of food for breakfast, lunch, and dinner. A large noisy, brown bear barged into camp the second night, got the food pack down from the tree where they had hung it, and ate one half of the food that was left. The next morning, after they all had breakfast, they found they had 4 servings of food left. They decided they had better hike back to their car. How many servings of food did they begin the trip with?

Explanation / Answer

let they started with x servings of food

they consumed 4*3 = 12 servings each day

so , in two days they have consumed 2*12 = 24 servings

now they are left with x - 24

bear ate 1/2 of this so now they are left with 1/2 ( x- 24 )

after having breakfast next say they are left with 1/ 2 ( x- 24 ) - 4

1/2 ( x- 24 ) - 4 = 4

1/2 ( x - 24 ) = 8

x - 24 = 16

x = 16 + 24

x = 40

so they started with 40 servings of food
