5x + 4x = 720 9x = 720 (divide by 9) X= 80 In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining) Work: 5(80)= 400
This is the equation you need to use: y = kx So, let's put it this way: y can be the total amount of money you spend (so $48), and x the number of people (6)
y=kx 48=k*6 k = 48/6 k = 8
The constant variation, and the price of one ticket is 8.
