Answer:
formula for maintenance cost:
maintenance cost = 1.7 visitors + 262.5
cost for 2,800,000 visitors $5,022,500
Step-by-step explanation:
We find and subtract low from high:
![\left[\begin{array}{ccc}High&4325&7615\\Low&1925&3535\\Diference&2400&4080\\\end{array}\right]](https://img.qammunity.org/2021/formulas/business/college/w5xybikhpbxtk4ty03ws6fvd51g8m07zbp.png)
With that we solve for the slope which is the variable cos:
cost 4080
Unis 2400
variable cost 1.7
now, we solve for the fixed cost:
Total Cost 7615.00
Variable 4325 x 1.7 = 7352.50
Fixed Cost 262.50
expected cost for 2,800 visitors:
(2800 x 1.7 + 262.5) x 1,000 = 5,022,500
