We are given that The monthly charge for a waste collection service is 1830 dollars for 100 kg of waste
So, 
We are also given that The monthly charge for a waste collection service is 2460 dollars for 135 kg of waste.
So, 
We are supposed to find a linear model for the cost, C, of waste collection as a function of the number of kilograms, w.
So, we will use two point slope form :
Formula : 
Substitute the values





y denotes the cost
x denotes the weight
So, Replace y with C and x with w

So, a linear model for the cost, C, of waste collection as a function of the number of kilograms, w is

<u><em>Answer:</em></u>Each brother gets </span>

<span> of a sandwich
<u><em>Explanation:</em></u>We know that the total number of sandwiches is 2 and that the number of brothers is 3.
Since we are given that the sandwiches will be divided equally among the three brothers, this means that each will get an equal share.
Therefore, to get the share of each, we will simply <u>divide the number of sandwiches by the number of brother</u>s as follows:
each one will get = </span>

=
