Respuesta :
1 adult equals approximately 1.36 children. ,1.36 only goes into 5 ,3 times. Therefore there can only be 3 extra adults.
The number of adults that can get in the considered elevator if thee are 10 children already in it is 4 adults.
How to form mathematical expression from the given description?
You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
Suppose that the capacity of the considered elevator be expressed in third form (neither in terms of children, nor in terms of adult), as 'k'.
So, we have: k = 15 children = 15x (say each children covers x capacity)
and k = 11 adults = 11y (say each adult covers y capacity)
(here, we assumed that capacity is linearly covered, ie if one person covers some capacity, then two person cover the sum of their covered capacity).
It is given that there are 10 children in the elevator right now.
That means, k-10x = 15x -10x = 5x capacity is still remaining.
Converting x to y, as shown below:
[tex]15x = 11y\\x = \dfrac{11y}{15}[/tex]
Thus, 5x is equivalent to:
[tex]5x = 5\left( \dfrac{11y}{15} \right) = \dfrac{11y}{3} = 3.6\overline{6}y[/tex]
It is smaller than 4y but bigger than 3y. Therefore, 3 more adults can come in it, as 4 will make the elevator get overloaded.
Thus, the number of adults that can get in the considered elevator if thee are 10 children already in it is 4 adults.
