Sagot :
The $1 belongs in the box.
What are the equations that represent the question assuming the $1 does not belong in the box?
s + c = 47 equation 1
5s + 4c = 200 equation 2
How many singles and couples bought the ticket assuming that the $1 does not belong in the box?
Multiply equation 1 by 5
5s + 5c = 235
Subtract equation 2 from equation 3
c = 35
Subtract 35 from 47
c = 47 - 35 = 12
35 couples tickets and 12 individual tickets were sold. This is not possible since the couples tickets were sold in 2.
What are the linear equations that represent the question if the 1 dollar belonged in the box?
s + c = 47 equation 1
5s + 4c = 201 equation 2
How many couples tickets were sold?
Multiply equation 1 by 5
5s + 5c = 235
Subtract equation 2 from equation 3
c = 34
34 is divisible by 2 so the $1 belongs in the box.
Here is the complete question:
Nola was selling tickets at the high school dance. At the end of the evening, she picked up the cash box and noticed a dollar lying on the floor next to it. She said,
I wonder whether the dollar belongs inside the cash box or not.
The price of tickets for the dance was 1 ticket for $5 (for individuals) or 2 tickets for $8 (for couples). She looked inside the cash box and found $200 and ticket stubs for the 47 students in attendance. Does the dollar belong inside the cash box or not?
