158, because due to PEMDAS you would do all the functions in the parenthesis first, then you would move on to multiplication, and finally you would find the sum of the equation
We will be dealing with a system of equations and we'll find the answer by using elimination.
M= members and N= non-members
M+N=353
2.75M+6.50N=1762
We can eliminate M by multiplying the first equation by -2.75.
-2.75m-2.75n=-970.75
2.75m+6.50N=1762
3.75n=791.25
Now divide
791.25/3.75=211
So there was 211 non-member tickets. All we have to do to find the number of member tickets is replace n with its value.
211+m=353
353-211=m=142
There are 142 member tickets. To check our answer, let's put both values in for the second equation.
2.75(142)+6.50(211)
390.50+1,371.50
1762
So, there were 142 members and 211 non-members that came to the play.
