The school that Stefan goes to is selling tickets to a choral performance. On the first day of tickets sales the school sold 3 senior citizen tickets and 1 child tickets for a total of $38. The school took $52 on the second day by selling 3 seinor citizen tickets and 2 child tickets. Find the price of the senior citizen ticket and the price of a child ticket
Let the cost of a senior ticket = S
Let the cost of a child's tickets = C
So
3S + 1C = 38 (1)
3S + 2C = 52 (2)
Subtract (1) from (2)
C = 14 this is the cost of a child's ticket ( in dollars)
Sub this into (1)
3S + 1 (14) = 38
3S + 14 = 38 subtract 14 from both sides
3S = 24 divide both sides y 3
S = 8 this is the cost of a senior ticket (in dollars)
