Answer:
$55.50
Explanation:
For a ticket that keeps travel cost as low as possible :
Since he only goes to work every third Saturday ;
A day return journey traveling Saturday or Sunday is better : $3.00
Since he goes to work everyday from Monday to friday:
A rover ticket for (Monday _ Friday) option is best : Cost = $17.50
Cost per week for 3 weeks(Monday - Friday) ; Hence,
$17.50 * 3
= $52.50
Total cost For 3 weeks :
Cost per week for 3 weeks (Monday - Friday) + cost of one saturday:
$52.50 + $3.00
= $55.50
