Answer:
Option A. ![C(d)=25d+12](https://tex.z-dn.net/?f=C%28d%29%3D25d%2B12)
Step-by-step explanation:
Let
d -----> the number of days
C(d) -----> the total cost
we know that
The linear equation in slope intercept form is
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the rate or slope of the linear function
b is the y-coordinate of the y-intercept
In this problem we have that
![C(d)=md+b](https://tex.z-dn.net/?f=C%28d%29%3Dmd%2Bb)
The slope of the linear equation is equal to the charge of $25 per day to board dogs
so
![m=25\frac{\$}{day}](https://tex.z-dn.net/?f=m%3D25%5Cfrac%7B%5C%24%7D%7Bday%7D)
The y-intercept is the value of y when the value of x is equal to zero
In this problem the C-intercept is the total cost when the number of days (d) is equal to zero
The C-intercept is equal to the cost of the bath $12
so
![b=\$12](https://tex.z-dn.net/?f=b%3D%5C%2412)
substitute the values
![C(d)=25d+12](https://tex.z-dn.net/?f=C%28d%29%3D25d%2B12)
For multiplying fractions you basically just multiply across so for the green one it would be 1x4=4 so you would have 4 as the numerator for the answer and the bottom is 2x8=16 so that would be the denominator your answer would be 4/16 for the green question
