The equation would be:
3.50 + 0.15x
x represents each 'late day'
There is no graph, so it is impossible to answer this question. I apologise.
Step-by-step explanation:
homework needs help and help needs homework
Consider the binomial
![\displaystyle{ (a+b)^\displaystyle{n](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%28a%2Bb%29%5E%5Cdisplaystyle%7Bn)
,
where n=0, 1, 2, 3, ...
For example
![\displaystyle{ (a+b)^0=1](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%28a%2Bb%29%5E0%3D1)
![\displaystyle{(a+b)^1=1a+1b](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%28a%2Bb%29%5E1%3D1a%2B1b)
![\displaystyle{(a+b)^2=1a^2+2ab+1b^2](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%28a%2Bb%29%5E2%3D1a%5E2%2B2ab%2B1b%5E2)
![\displaystyle{ (a + b)^3 = 1a^3 + 3a^2b + 3ab^2 + 1b^3](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%28a%20%2B%20b%29%5E3%20%3D%201a%5E3%20%2B%203a%5E2b%20%2B%203ab%5E2%20%2B%201b%5E3)

Consider the Pascal's triangle, as shown in the picture, where the very first row is denoted by row 0, the second by row 1, the third by row 2 and so on...
We notice that the coefficients of the expansion of
![(a+b)^n](https://tex.z-dn.net/?f=%28a%2Bb%29%5En)
, are the entries in the
![n^{th}](https://tex.z-dn.net/?f=n%5E%7Bth%7D)
row of Pascal's triangle.
