Wonderlic practice question please help!!

Published

I'm practicing online off Wonderlic and it does explain the break down on the algebra questions but not a complete break down on this one

9$ per adult. Seniors 6$. Capacity 80people. It's full capacity and movie theater has made 675$. How many seniors bought the ticket?

I know it's probably a dumb question to some but I been out of school for awhile and I'm also brushing up on math thank you to whoever can help.

to set it up you would think

(9$ x the number of adult tickets) + (6$ x (total number of tickets sold - number of adult tickets)) = 675$

was the answer given 15?

Thank you can you so written out would be

9$X + 6X-80=675$ ? Sorry I'm brushing up on math and need deep details

9x + 6(80-x) = 675

Actually for the 9x+6(80-x)=675 answer is 65 and the answer for the story problem is 15:(

If anyone can write it out will be awesome and explain thank you

no .. x is the number of adult tickets sold --- so 80-x is the number of senior tickets sold.

80 - 65 = ?
