Agroup of mountain climbers begin an expedition with 250 pounds of food. they plan to eat a total of 12 pounds per day.

The expedition will last for approximately 20 days with this amount of food carried.

Step-by-step explanation:

We are given the following information in the question:

Amount of food carried by mountain climbers = 250 pounds

Amount of food eaten per day = 12 pounds.

Number of days the expedition can last =

Hence, the expedition will last for approximately 20 days with this amount of food carried.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
