Answer 2

Given:

The cost for the children’s party at the rollerskating rink is a function of n, the number of people in the party. The cost function, C is given by

$C(n)=\left\{\begin{array}{ll}150, & 0$

We need to determine the cost to have a party with 9 people and the cost to have a party with 20 people.

Cost of having the party:

From the given function, the cost of having the party for 9 people lies in the interval $0$

Hence, the cost of having the party for 9 people is 150.

Also, from the function, the cost of having the party for 20 people lies in the interval $12$

Hence, the cost of having the party for 20 people is 260.
