A shipping container will be used to transport several 110-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23,000 kilograms. Other shipments weighing 3,800 kilograms have already been loaded into the container. Which inequality can be used to determine [tex] c [/tex], the greatest number of 110-kilogram crates that can be loaded onto the shipping container?

A. [tex] 23,000 \geq 3,800 + 110c [/tex]

B. [tex] 23,000 \leq 3,800 + 110c [/tex]

C. [tex] 23,000 \geq 110(c + 3,800) [/tex]

D. [tex] 23,000 \leq 110(c + 3,800) [/tex]

Answer :

Sure, I can help with that!

The problem requires us to find the greatest number of 110-kilogram crates, represented by [tex]\( c \)[/tex], that can be added to the shipping container without exceeding its weight limit.

Here's how you can determine this:

1. Understand the total weight capacity: The shipping container has a weight capacity of 23,000 kilograms.

2. Account for already loaded weight: The container already has shipments weighing 3,800 kilograms.

3. Calculate remaining capacity: Subtract the weight of the other shipments from the total capacity to find out how much weight you can still add:

[tex]\[
\text{Remaining weight capacity} = 23,000 - 3,800 = 19,200 \text{ kilograms}
\][/tex]

4. Determine crate weight: Each crate weighs 110 kilograms.

5. Set up the inequality: To find the greatest number of crates [tex]\( c \)[/tex], you want the total weight of these crates plus the already loaded shipments to remain within the 23,000-kilogram limit:

[tex]\[
3,800 + 110c \leq 23,000
\][/tex]

6. Solve the inequality: Subtract 3,800 from 23,000 to find out how much weight can be dedicated to the crates:

[tex]\[
110c \leq 19,200
\][/tex]

Now, divide both sides by 110 to solve for [tex]\( c \)[/tex]:

[tex]\[
c \leq \frac{19,200}{110}
\][/tex]

Performing the division gives:

[tex]\[
c \leq 174.5454\ldots
\][/tex]

7. Determine the greatest whole number: Since [tex]\( c \)[/tex] must be a whole number, we need the largest integer value that satisfies the inequality:

[tex]\[
c \leq 174
\][/tex]

Therefore, the greatest number of 110-kilogram crates that can be loaded into the shipping container is 174. The correct inequality to express this situation is [tex]\( 23,000 \geq 3,800 + 110c \)[/tex].
