Given:
Number of people bought tickets for comedy = 
Number of people bought tickets for horror = 
Number of people bought tickets for kids movie = 
To find the number of people who bought tickets for the action movie.
Let us take,
Total number of tickets = 1
Now,
Total number of tickets for comedy, horror and kids movie are = 
So,

LCM of 5,4,10 = 20
= 
= 
Rest are action movie's tickets.
Therefore,
Number of action movie tickets = 
= 
= 
Hence,
The number of people who bought the tickets for action movie is
.
In order to find the intercepts you have to get the variable by itself and the equation is y-intercept form.
The x intercept is -8 so (-8,0)
The y intercept is 8 so (0,8)
The slope is 1x
If the problem is 6r•s•4rt•10rst, then the answer is 240•r^3•s^2•t^2.
14. t=d/r
15. m=e/c^2
16. c=-p+r
Yes because $56 + 6.25% = 56.0625
And 15% of 56.0625 is 8.409375
So, 56.0625 + 8.409375 = $64.471875 making the total right under $65.
