Answer:
15
Step-by-step explanation:
The calculation is:
endamount - startamount divided by number of days.
(237-27) / 14 = 15
X=5
each side of the small triangle is multiplied by 5 to make the larger triangle and 4x5 is 20. So 20-8=12. And 3x4 is 12.

Step-by-step explanation:
<em>Incomplete Question: This question requires options</em>
Let the amount received be represented with y
Let the number of boxes be represented with x
From the question, we have that:
x = 5
; y = 13.50
Multiply the values of x and y by 2Similarly,
x = 10; y = 27
This gives:
![(x_1,y_1) = (5,13.5)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%20%285%2C13.5%29)
![(x_2,y_2) = (10,27)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%2810%2C27%29)
The slope of the graph is calculated as follows:
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
![m = \frac{27 - 13.5}{10 - 5}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B27%20-%2013.5%7D%7B10%20-%205%7D)
![m = \frac{13.5}{5}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B13.5%7D%7B5%7D)
![m = 2.7](https://tex.z-dn.net/?f=m%20%3D%202.7)
The equation of the graph is calculated as follows:
![y - y_1 = m(x - x_1)](https://tex.z-dn.net/?f=y%20-%20y_1%20%3D%20m%28x%20-%20x_1%29)
Substitute values for m, x1 and x2
![y - 13.5 = 2.7 * (x - 5)](https://tex.z-dn.net/?f=y%20-%2013.5%20%3D%202.7%20%2A%20%28x%20-%205%29)

![y - 13.5 = 2.7x - 13.5](https://tex.z-dn.net/?f=y%20-%2013.5%20%3D%202.7x%20-%2013.5)

![y = 2.7x - 13.5 + 13.5](https://tex.z-dn.net/?f=y%20%3D%202.7x%20-%2013.5%20%2B%2013.5)
![y = 2.7x](https://tex.z-dn.net/?f=y%20%3D%202.7x)
The above equation can be used to determine the graph

15 x 8 is 120 so he watches 120 minutes a day
9000/120 is 75 days
So the answer is 75 days
