Nine friends went on a camping trip a campsite costs 40 per night for the first 4 people and campers can pay an extra fee for each additional person if the group of friends rented one campsite for one night and paid 80 how much did the campground charge for each additional person

8 dollars per extra person

Step-by-step explanation:

subtract the original 40 dollars from 80 ,you get 40,the probloem tells you that there is 9 people meaning there was 5 extras ,so 40/5=8

$8 charge for each additional person

Step-by-step explanation

$40/night for each person

First 4 people already paid.

Leftover are 5 people.

9-4=5

Since first 4 people paid, the rest to be paid is $40.

$80-$40=$40

To find the charge for each person, divide the amount of money left by the amount of people left.

40÷5= 8

$8 is the additional charge for each additional person.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
