During the summer, Anita works on her uncle's dairy farm. One of Anita's many chores is to load bales of hay onto a wagon and haul them from the field into the
barn. There is a proportional relationship between the number of wagon loads, x,
and the number of bales of hay Anita can haul, y.
The equation that models this relationship is y = 6x.
How wagon loads does it take Anita to haul 18 bales of hay? Write your answer as a whole
number or decimal
