Answer:
11.50x - $10.23 = $81.77
Step-by-step explanation:
$11.50 is how much he made per hour and X is the number of lawns he mowed, but we don't know exactly how many.
$11.50x tells us how much money he made.
He spent some of that money, $10.23, on maintenance so
$11.50x - $10.23 he spent = $81.77 which is the amount of money they said he has left
