Here is how to set up the equations:
x = number of adult tickets sold
y = number of student tickets sold
3x + 2y = 824
x = 2y
now you can substitute eq2 into eq1
3(2y) + 2y = 824
8y = 824
y = 103 tickets
and therefore
x = 206 tickets
Please help... Tickets for a concert were sold to adults for $3 and to students for $2. If the total receipts were $824 and twice as many adult tickets as student tickets were sold, then how many of each were sold.
I'm having problems setting up equation. Thanks.
