A particular movie theater charges $9.00 per adult and $2.50 per child. Suppose 400 people attended a movie and the total revenue from ticket sales was $2300.
Write linear equations for the two constraints, where a represents the number of adults attending the
movie and y represents the number of children attending the movie.

Step-by-step explanation:

Since X and Y represent the total number of adults and total number of children respectively,

total number of people attended the movie

price for the ticket for adult is $9 and x adults are attending movie so total sale for adults is 9x

The price for the ticket for child is $2.50 and y children are attending the movie so total sale for children is 2.50y

which is total 2300.

So

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
