A school sales 200 tickets for $475.00. Adult tickets are $3.00 and student tickets are $2.00. How many $2.00 and $3.00 tickets were sold. I have answer by guessing only. I need help putting together a formula.
You need to set up 2 equations for your 2 unknowns.
x+y=200 (x is the $3 ticket and y is the $2 ticket)
3x + 2y= 475 (the sum of all tickets sold is 475)
In the first equation solve for x:
Now plug in x in the second equation:
3(200-y) +2y = 475
600-3y+2y = 475
600 -y = 475
-y = -125
Now plug y into the first equation:
So there were 75 $3 tickets sold and 125 $2 tickets sold
