Answer:
Lisa can shelve at least 6 books in 1 minute time.
<u>Explanation:</u>
Given:
The public library has volunteers shelve book after they have been returned.
Lisa shelve 165 book in 25 minutes.
Patricia shelves 198 books in 45 minutes.
To Find:
We have to find how many can Lisa shelve each minute?
Solution:
Now, we know that, number of books she can shelve =
Number of books she can shelve = = 6.6
Hence, she can shelve at least 6 books in 1 minute time.
For this case, the first thing we must do is define variables.
We have then:
x: number of cabins
y: number of campers
We now write the equation that models the problem:
We know that there are 148 campers.
Therefore, substituting y = 148 in the given equation we have:
From here, we clear the value of x:
Therefore, the number of full cabins is:
Answer:
The number of full cabins is:
