Question 177562
let c and a be the number of children and adult tickets sold, respectively
:
5c+8a=2500.....eq 1
5(3c)+8(a/2)=2500....eq 2--->15c+4a=2500
:
5c+8a=2500.....eq 1
15c+4a=2500....eq 2
:
multiply eq 2 by -2 and add the two equations together thus eliminating the a terms. We are left with -30c+5c=-5000+2500
:
-25c=-2500
