Matt and 2 of his friends would like to go to the fair. It costs 5 dollars per person to get in the gate and 1 dollar per ticket. If Matt and his friends want to get in the gate and buy 50 tickets, how much will it cost all together.
3
The equation to my problem is y=$5.00(50x1) X =the number of people Y = the total cost
4
The independent variable is my x which is the number of fair tickets The dependent variable is my y which is the total cost. Y DEPENDS on x So the total cost DEPENDS on the number of the fair tickets
5
x$5.00xy( x, y) 15.00(1)$5.00(1, 5) 25.00(2)$10.00(2, 10) 35.00(3)$15.00(3, 15) 45.00(4)$20.00(4, 20) 55.00(5)$25.00(5,25)
6
Domain is the x values Range is the y values So my domain is {1,2,3,4,5} My range is {5, 10, 15, 20, 25} R A DOMAIN G E
7
Since my data contains points then it is a continuous graph. You can not purchase 1 ½ tickets, you can only purchase the tickets by 1, 2, 3, etc.So we will not use any of the numbers that are between 1 and 2.
8
A function is where there is one independent value paired with exactly one dependent value. This means that the x values Can't repeat. My X values do not repeat, then it IS a FUNCTION!
10
The amount of friends that went with Matt to the fair, it could cost for just her $5 or with up to 5 of her friends –$25 And that is without the fair tickets. I wonder how much that would be…..now add the $50 for tickets
