517. A long-distance telephone call costs $2.40 plus $0.23 per minute. If the call is not an
integer number of minutes, the caller is charged $0.23 for the fraction of a minute. Write
an inequality that states that an x-minute call costs at most $5.00. Solve the inequality to
find the maximum number of minutes that it is possible to talk without spending more than
$5.00.
