Given :
A graph of Total Meals Packed vs Time( in hours ).
To Find :
How many meals would be packed in 20 hours.
Solution :
First we will find the equation of line.
Now, the line passes through ( 0, 0 ) and ( 4, 500 ).
So, equation of line passing through ( 0, 0 ) and ( 4, 500 ) is :
![y - 0 = \dfrac{500-0}{4-0}( x - 0 )\\\\y = 125x](https://tex.z-dn.net/?f=y%20-%200%20%3D%20%5Cdfrac%7B500-0%7D%7B4-0%7D%28%20x%20-%200%20%29%5C%5C%5C%5Cy%20%3D%20125x)
Now, putting the value of x = 20 hours in above equation, we get :
y = 125 × 20 meals
y = 2500 meals
Therefore, number of meals packed in 20 hours is 2500 meals.
