For safety, each climber has 8 hooks when climbing the mountain. A large group of climbers climbs up a mountain and puts all their supplies in a heap in a cabin. One of the climbers wishes to know the number of climbers in the group, so he counts the number of hooks in the supply heap. If the climber counts [tex]$h$[/tex] hooks, which of the following functions can be used to find the number of climbers, [tex]$c(h)$[/tex], in the group?

Choose 1 answer:

(A) [tex]$c(h)=\frac{h}{64}$[/tex]

(B) [tex][tex]$c(h)=\frac{h}{8}$[/tex][/tex]

(C) [tex]$c(h)=8h$[/tex]

(D) [tex]$c(h)=64h$[/tex]



Answer :

To solve this problem, let's follow a step-by-step approach to determine how to find the number of climbers, [tex]\( c \)[/tex], in the group given that the climbers have [tex]\( h \)[/tex] hooks in total.

1. Identify the information given:
- Each climber has 8 hooks.
- The total number of hooks counted is [tex]\( h \)[/tex].

2. Understand the relationship between the hooks and the climbers:
- If one climber has 8 hooks, then the number of climbers would be the total number of hooks divided by the number of hooks per climber.

3. Formulate the equation:
- Since each climber has 8 hooks, if there are [tex]\( c \)[/tex] climbers, the total number of hooks is [tex]\( 8c \)[/tex].
- We can set up the equation as:
[tex]\[ 8c = h \][/tex]

4. Solve for the number of climbers, [tex]\( c \)[/tex]:
- To find the number of climbers, [tex]\( c \)[/tex], we need to isolate [tex]\( c \)[/tex] in the equation:
[tex]\[ c = \frac{h}{8} \][/tex]

5. Match this with the given options:
- The function that can be used to find the number of climbers, [tex]\( c(h) \)[/tex], given [tex]\( h \)[/tex] hooks is:
[tex]\[ c(h) = \frac{h}{8} \][/tex]

Therefore, the correct answer is:
(B) [tex]\( c(h) = \frac{h}{8} \)[/tex].
