The answer is 32
8 x 6 = 48
80 - 48 = 32
$29.50 + $10.50 = $40
Answer: They gave her $40!
ANSWER

EXPLANATION
The given function is

We need to find the inverse of this function,
Let

We interchange x an y to obtain,

We solve for y now to obtain,

We divide through by m to get,

Hence the inverse function is ,

For this inverse to exist, the denominator must not be equal to zero,
Thus

The correct answer is A.
First combine like terms so
2x+6=3x-8
3x - 2x =1X
-6 - -8= -14
1X ÷ -14
then just divide
