Prom tickets beforehand were $31 and at the door they were $40 a total of 200 tickets were sold. Total money collected for both was 6,641.00
- How many tickets were sold at the door?
Let beforehand tickets sold be x
door tickets sold be y
x+y = 200................1
Value equation
31x+40y = 6641...........2
Multiply (1) by 31
31x+31y=6200
31x+40y = 6641
subtract
-9y = -441
y =49
you can calculate x by plugging y

Here is a quick mental math way to solve problems like this....
If all 200 tickets were $40 tickets, the total would have been $8000; that is $8000-$6641 = $1359 more than the actual total.
The difference between the two ticket prices is $9, so the number of $31 tickets was 1359/9 = 151.
151 tickets were sold beforehand; 49 were sold at the door.
