A group of people signed up for a bus tour that costs a total of $1120. If they can increase the size of their group by 7 people, the amount each person has to pay decreases by $8. How many people are currently signed up?

160

Step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
