hello
from the question given, the dog walker charges a flat rate of $6 and an extra $30 per hour.
we can write out an equation in function notation
let the number of hours be represented by x
![f(x)=6+30x](https://tex.z-dn.net/?f=f%28x%29%3D6%2B30x)
now we can proceed to solve the cost of the walk for 45 minutes
![\begin{gathered} 1hr=60\min s \\ \text{xhr}=45\min s \\ x=\frac{45}{60} \\ x=\frac{3}{4} \\ \text{therefore 45mins = 3/4 hours} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%201hr%3D60%5Cmin%20s%20%5C%5C%20%5Ctext%7Bxhr%7D%3D45%5Cmin%20s%20%5C%5C%20x%3D%5Cfrac%7B45%7D%7B60%7D%20%5C%5C%20x%3D%5Cfrac%7B3%7D%7B4%7D%20%5C%5C%20%5Ctext%7Btherefore%2045mins%20%3D%203%2F4%20hours%7D%20%5Cend%7Bgathered%7D)
now we can input the value into the equation and know the cost for 45 minutes walk
![\begin{gathered} f(x)=6+30x \\ x=\frac{3}{4} \\ f(x)=6+30(\frac{3}{4}) \\ f(x)=6+22.5 \\ f(x)=28.5 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%28x%29%3D6%2B30x%20%5C%5C%20x%3D%5Cfrac%7B3%7D%7B4%7D%20%5C%5C%20f%28x%29%3D6%2B30%28%5Cfrac%7B3%7D%7B4%7D%29%20%5C%5C%20f%28x%29%3D6%2B22.5%20%5C%5C%20f%28x%29%3D28.5%20%5Cend%7Bgathered%7D)
from the calculation above, the cost of 45 minutes walk will cost $28.5
Yeah that's right I'm pretty sure that's the work u do so u r not wrong ok so relax
Answer:
See below
