Question

The cost of a school banquet is $95 plus $15 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

Answer 1

So, y = mx + b.

Identify the variables

m is for how many people is attending to the school banquet.

x is for the cost for each person attending

b is for the cost of a school banquet

m = 77, x = 15, b = 95

Now plug in the variables

y = 77(15) + 95

Solve:

77 (15) = 1155

1155 + 95 = 1250

Your answer is $1250.
