Help me please

Tyler filled a small jar with quarters and dimes and
donated it to his school's charity club. The club member
receiving the jar asked, "Do you happen to know how
much is in the jar?" Tyler said, "I know it's at
least $8.50, but I don't know the exact amount."
Write an inequality to represent the relationship
between the number of dimes, x, and the number of
quarters, y, and the dollar amount of the money in the
jar.
(It will say "CORRECT" when you type in the correct
inequality.)
