Problema Solution

The school that Jack goes to is selling tickets to a fall musical. on the first day of ticket sales the school sold 2 adult tickets and 2 student tickets for a total of $44. the school took $88 on the second day by selling 2 adult tickets and 6 student tickets. find the price of an adult ticket and the price of a student ticket.

Answer provided by our tutors

Adult ticket price will be x

Student ticket price will be y

 

First Equation:

2x + 2y = 44

Second Equation

2x + 6y = 88

 

Make both equations equal to 0 

2x + 2y - 44 = 0

2x + 6y - 88 = 0

 

and make them equal to each other

2x + 2y - 44 = 2x + 6y -88

move around the variables

2x-2x  + 2y - 6y - 44 + 88 = 0

-4y + 44 = 0

4y = 44

y = 11

 

plug it in to an equation

2x + 2y = 44

2x + 2(11) = 44

2x + 22 = 44

2x = 44 - 22

2x = 22

x = 11

hence x = 11 and y = 11
