Correct answer is option D.

The solution is listed below

F(x)=4x+7 \\  \\ 
y=4x+7 \\  \\ 
y-7=4x \\  \\ 
 \frac{y-7}{4}=x \\  \\ 
 x= \frac{y-7}{4} \\  \\ 
f-^{1}(y) = \frac{y-7}{4} \\  \\ 
f-^{1}(x) = \frac{x-7}{4} \\  \\

HACTEHA [7]

250 = 167.93 + x

[She needs $250, she has $167.93, and she needs x more. x represents the amount of money she still needs in order to get 250]

250 = 167.93 + x Subtract 167.93 on both sides

250 - 167.93 = 167.93 + x - 167.93

250 - 167.93 = x

82.07 = x


She needs $82.07 more



Or you could have done:


250 - 167.93 = 82.07
