Suppose you & your friends are going to the movies.The amount of money you spend for tickets varies directly with the number of people buying tickets.If you spend $48 for six tickets ,What is the constant of variation?
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.
