the cost of a banquet is $95.00 plus $15.00 for each person attending. write an equation that gives total cost as a function of the number of people attending. what is the cost for 77 people?
cost = 15n + 95 , where n is the number of people attending
replace n with 77 and evaluate to get the cost
To write the equation that gives the total cost as a function of the number of people attending, we can start by defining the variables involved:
Let "C" represent the total cost and "N" represent the number of people attending.
We have two components to consider: the fixed cost of $95.00 and the additional cost of $15.00 per person.
The equation can be written as follows:
C = 95 + 15N
To calculate the cost for 77 people, we substitute N = 77 into the equation:
C = 95 + 15 * 77
C = 95 + 1155
C = 1250
The cost for 77 people would be $1250.00.
