Question

The cost of a school banquet is $65 plus $13 for each person attending. How do you determine the linear equation that models this problem and what is the cost for 81 people?

Answer 1

`c(p) = 65+13p`
`color(white)("XXXX")`where `c(p)` is the cost function and `p` is the number of people attending.
`c(81)= 1128` (dollars)

Explanation:

`c(81) = 65 + 13(81) =1128`
