Okay so in this question it says to solve f(7). This means to plug in the 7 every where you see an x, so that it looks like this: 
Then you'll solve it like a normal equation.
Hope this helped! Let me know if there is anything I need to clarify or explain more in depth!
A=p(1+r)^t
A=15,000×(1+0.06)^(5)
A=20,073.38

Answer:
2s = 16
Step-by-step explanation:
In the choir, there are 16 altos and s sopranos.
Let the number of altos be a.
=> a = 16
There are twice as many sopranos as altos.This means that:
a = 2s
Since the number of altos, a, is 16, the equation that represents this situation is:
2s = 16
