The cost of a school banquet is $75+30n, where n is the number of people attending.

If 53 people are attending to visit school banquet, then you have to find the value of given expression at n=53.

At n=53, the value is $(75+30·53)=$1,665.

ANSWER

$1665

EXPLANATION

The relation given to you is the relation between the number of people and the cost, which can be written in a function notation as

[tex]c(n) = 75 + 30n[/tex]

You just have to plug in

[tex]n = 53[/tex]
in to the cost function and simplify.

[tex]c(n) = 75 + 30n[/tex]

[tex]c(53) = 75 + 30(53)[/tex]

[tex]c(53) = 75 + 1590[/tex]

[tex]c(53) = 1665[/tex]

Therefore the cost for 53 people is $1665
