Answer:
It would cost $160 for 15 people to rent the bowling alley
Step-by-step explanation:
First, let's identify what we know:
1) It costs $100, just to rent the bowling alley.
2) We have to add $4 dollars, for every extra person.
3) The total cost can be found by using the expression 100 + 4n = x (n equals number of people, x equals total cost, 100 equals intial rent charge, and 4 equals the charge for each individual person)
So, just input 15 into the equation!
100 + 4(15) = x
100 + 60 = x
x = $160
