Answer 1

jia's friend should charge $22.33 for the dog washing sevice.

Explanation:

It is given that jia's friend provide fog washing service for each dog supplies cost $4 and wage are $5 .

A special room and equipment are needed ,at a cost of 400$ per month .

Fixed cost = $400

Variable cost = $4+$5=$9

Total cost of 30 dogs is

`C=400+9(30)=670`

Let x be the amount charged by jia's friend for the dog washing sevice. So, total revenue for 30 dogs washing service is

`R=30x`

Formula for profit:

`Profit=Revenue-Cost`

`Profit=30x-670`

For break even condition, the profit is 0.

`0=30x-670`

`-30x=-670`

`30x=670`

Divide both sides by 30.

`(30x)/(30)=(670)/(30)`

`x=22.33`

Therefore, jia's friend should charge $22.33 for the dog washing sevice.
