I believe the equation that would relate x and y would be in the form of:
y = x t
where the variables represent:
x is the amount you earn per hour ($ per hour)
y is the total amount you earn ($)
t is the total number of hours (hours)
We can solve x by plugging in the initial values of y and t which is given in the problem. That is:
y = $42.25 and t = 6.5 hours
therefore:
$42.25 = x (6.5 hours)
x = $6.5 per hour
Hence you earn 6.5 dollars for every hour of cleaning the community park.
