Answer:
10 friends got into the fair
Explanation:
If county fair cost is $2.5 per person
$10 to catch a trolley
total cost = $35
Total county fair cost= total cost - trolley cost
= $35 - $10
= $25
So if $25 was spent on county fair, then the number of friends that went is
$25/$2.5 = 10
That is total cost divided by cost per person gives number of persons
