Answer:
$40
Step-by-step explanation:
If you were to purchase 7 picture frames, you would replace x in the equation with 7, this is shown below.
<u>f(x)=9x-23 ---> f(x)=9(7)-23</u>
Now we can solve for f(x). First start with 9(7).
<u>f(x)=9(7)-23 ---> f(x)=63-23</u>
Now finish the last part by subtracting 23 from 63.
<u>f(x)=63-23 ---> f(x)=40</u>
This means that you would have to pay $40 dollars to purchase the 7 picture frames.

Step-by-step explanation:
Molly should have multiplied three first so that it would have been
x + 6 + 3x + 12
4x + 18
Dylan did not add x to 5x
it should have been
6x - 12
Jose did not multiply 7 and -5
it should have been
x + 3 + 7x - 35
8x - 32
