Given :
The admission tickets to an exhibition at $5 for an adult and $2 for a child.
A family of 3 adults and 4 children visited the exhibition.
To Find :
What would be the charge if $50 note was used to buy the tickets.
Solution :
Charge of 3 adult ticket is, A = $( 5 × 3 ) = $15 .
Charge of 4 children ticket is, C = $( 4 × 2 ) = $8 .
Total amount to pay is :
T = $( 15 + 8 )
T = $23
Therefore, they get $( 50 - 23 ) = $27 change.
