Answer: Hello there!
we know that Jordan spent a total of $14.85 on the trip.
He spends $2.85 on snacks and the rest on bus fares.
the amount spend on bus fares is the difference between the total amount spend and the amount that he spends on snacks, this is:
$14.85 - $2.85 = $12
now we also know that he takes two buses ( one to the zoo, and other from the zoo)
then in two buses, he spended $12, this means that he spends $12/6 = $6 on each bus.
