Answer:
9.7
Step-by-step explanation:
For better representation, I think the function is written as:
B(x) = 40.00 - 0.08x
This is much more comprehensive. The variable x represents the number of prints. So, if x=40 prints, we replace this to the x in the equation to find the balance B.
B = 40 - 0.08(40)
<em>B = $36.8</em>
Answer:
more Sonia study than James.
Step-by-step explanation:
Given:
Sonia studied for 2 1/3 hours for the math test james studied 3/4 as long as Sonia.
Now, to find hours more Sonia study than james.
Sonia studied = ![\frac{7}{3} \ hours.](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%20%5C%20hours.)
James studied = ![\frac{3}{4} \ hour.](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%5C%20hour.)
Now, to get the more hours Sonia study than James we subtract the hour James studied from hours Sonia studied:
![\frac{7}{3} -\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%20-%5Cfrac%7B3%7D%7B4%7D)
![=\frac{28-9}{12}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B28-9%7D%7B12%7D)
![=\frac{21}{12}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B21%7D%7B12%7D)
![=\frac{7}{4}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7%7D%7B4%7D)
![=1\frac{3}{4}\ hours.](https://tex.z-dn.net/?f=%3D1%5Cfrac%7B3%7D%7B4%7D%5C%20hours.)
Therefore,
more Sonia study than James.
