The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.

Answer:

price of senior citizen ticket is $8 and price of child ticke be $14.

The plot is as attached. the ordered pair is (8,14)

Explanation:

Let price of senior citizen ticket be $x and price of child ticke be $y.

we are given that On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38.

Then we can write


3x+y=38..(i)

The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets.

So we can write


3x+2y=52...(ii)

Now solve above two equations togethere we get


3x+2(38-3x)=52\\3x+76-6x=52\\-3x=52-76\\-3x=-24\\x=8


y=38-3*8\\y=38-24\\y=14\\

price of senior citizen ticket is $8 and price of child ticke be $14.

In slope intercept form the above equation can be written as


y=38-3x


y= - (3/2)x+26

The plot is as attached. the ordered pair is (8,14)
