Answer:
Step-by-step explanation:
Cost of renting bowling alley = $ 100
Additional cost of renting bowling alley per person = $ 4
⇒ Total Cost for n no. of people = 100 + 4 × n
So, Cost for 15 people = Fix $100 for bowling alley
+ $4 for each 15 people
= 100 + 4 × 15
= 100 + 60
= 160
Therefore, The cost for 15 people equals to $ 160.
