6+6x you multiply 3 and 2 but you can’t add the 6x because the first 6 doesn’t have an x so it would stay as 6+6x

$f(x)=x^2-81\\
y=x^2-81\\
x^2=y+81\\
x=\pm \sqrt{y+81}\\
f^{-1}(x)=\pm \sqrt{x+81}\\$

$f(x)=2x-6\\
y=2x-6\\
2x=y+6\\
x=\dfrac{1}{2}y+3\\
f^{-1}(x)=\dfrac{1}{2}x+3\\
f^{-1}(2)=\dfrac{1}{2}\cdot2+3\\
f^{-1}(2)=1+3\\
f^{-1}(2)=4$

I think $6.75 for 15 juice boxes is better because, each juice box is 0.45.

While $5.50 for 11 juice boxes is 0.50.

And if we were to add 0.50 enough times to make 15 juice boxes it would equal 7.50

RIP OFFFFFFF

THE SECOND ONE IS A WAY BETTER OF A DEAL

1/10 is equal to 0.10
