tickets to a school dance were sold $2.00 in advance and $3.00 at the door. in all 194 tickets were sold for a total of $430. how many tickets were sold at the door?
Answer provided by our tutors
let 'x' represent the number of tickets sold at the door, then '194-x' represents the number of tickets sold in advance and we have:
430=3x + 2(194-x)
solving for 'x' we have x=42
42 tickets were sold at the door
