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
Part A:
Electricity Company | Rate Charged | Rate Rounded |
Atlas Energy 12.065 12.070
Big City Light 9.138 9.140
Connex 9.143 9.140
Dynamon Power 9.707 9.710
ElectriCo 9.503 9.500
Part B:
Big City Light and Connex.
Part C:
Two companies can have the same rate when they are rounded because two numbers can be rounded to the same number although they are different numbers. For example; 9.138 and 9.143 can both be rounded to 9.140.
