2nd or 3rd option I hope I narrowed it down
V = a * b * c
V = 30
a = 5
b = 2
c = ?
30 = 5*2*c
30 = 10*c
c = 30/10 = 3
c = 3
Each book costs $34 for this problem you need to first subtract 18 from 324 which gets you 306 then divide 306 by 9 and you get 34
Answer:

Step-by-step explanation:
<u>Two-Variable Functions</u>
A function expresses the relation between two variables in such a way that for each input for the independent variable n, there one and only one value for the function h(n). If it's explicitly given as an equation, then we can use values for n as we wish, and compute the different values of h(n).
The question provides the following function

We are required to find h(2), which can be computed by replacing n by the value of 2
