All you have to do is add how much she withdrew to how much she has left.
548 + 225 = 773
So Brita originally had $773 in her account.
To calculate the inverse isolate x on one side and switch x with y on both sides
1)
y=(2x-3)/5
5y=2x-3
5y+3=2x
(5y+3)/2=x
-> f(x)=(5x+3)/2
2)
y=(x+8)/2
2y=x+8
2y-8=x
-> f(x)=2x-8
3)
y=(x+2)/7
7y=x+2
7y-2=x
-> f(x)=7x-2
4)
y=(1-2x)/x
y=(1/x)-2
y+2=1/x
x=1/(y+2)
-> f(x)=1/(x+2)
The answer is A! If 1/3 is gone, there’s 2/3 left. To find how much 2/3 is, you would multiply 80 by 2/3
