For the school play, the advance tickets cost $3, while tickets at the door cost $5. there were twice as many tickets sold at the door as were sold in advance, and $4030 was collected. how many of each kind of ticket were sold?

Step-by-step explanation:

Let x represent the number of advance tickets sold

Let y represent the number of tickets sold at the door.

There were twice as many tickets sold at the door as were sold in advance. This means that

y = 2x

For the school play, the advance tickets cost $3, while tickets at the door cost $5 and a total of $4030 was collected. This means that

3x + 5y = 4030 - - - - - - - - - -1

Substituting x = 2y into equation 1. It becomes

3× + 5×2x = 4030

3x + 10x = 4030

13x = 4030

x = 4030/13

x = 310

y = 2x

y = 310×2 = 620 tickets

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
