Answer
Let x be a constant for the number of times the lawn has been mowed. Let y be the resulting money earned after mowing the lawn for x times.
$y=7.50x$
Work Step by Step
You can see in the table that \$7.50 is earned when 1 lawn is mowed. For each additional lawn, another \$7.50 is earned.
Therefore, for each lawn mowed, \$7.50 is earned.
So if there is multiple lawns, you multiply the lawns to 7.50.
EX.--> 8 lawns mowed * $7.50 = $60.00
