Bean is selling tickets to his annual fear factor competition where contestants factor expressions for prizes. On the first day of ticket sales he sold 4 adult tickets and 12 child tickets for a total of $80. He then took in $92 on the second day by selling 10 adult tickets and 3 child tickets. Find the price of an adult ticket and the price of a child ticket.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

2 2/3 hours duhh silly
