Louis petit, a manager of doggone gorgeous, inc., was reviewing the water bills of a dog daycare and spa. he determined that its highest and lowest bills of $3,800 and $2,000 were incurred in the months of may and november, respectively. if 600 dogs were washed in may and 200 dogs were washed in november, what was the fixed cost associated with the company's water bill? (round any intermediate calculations to the nearest cent and your final answer to the nearest dollar.)

Fixed cost = $1100

Explanation:

given data

Highest bill = $3,800

lowest bills = $2,000

dog washed in May = 600

dog washed in November = 200

to find out

fixed cost associated with the company's water bill

solution

first we get here variable cost that is express as

variable cost = (Highest bill - Lowest bill) ÷  ( Dogs washed may - Dogs washed November )  ...........1

put here value we get

variable cost =

variable cost = $4.5 per dog

so fixed cost will be here as

Fixed cost = Total cost to wash 600 dogs - Variable cost to wash 600 dogs

Fixed cost = $3800 - $4.5 × 600 dogs

Fixed cost = $3800 - $2700

Fixed cost = $1100
