Rover's Friends: Calculating the Break-Even Price for Dog Washing

[Ursus1]

Rover’s Friends provides dog washing services. For each dog, supplies cost $3 and wages are $5. To provide this service, a special room and equipment are needed, at a cost of $300 per month. Rover’s Friends maintains an average of 30 dogs washed each month. What must Rover’s Friends charge as a price for the dog washing service to break even?
(a) contribution margin;
(b) contribution rate;
(c) break-even point in sales dollars

Thank you

monthly cost ...

30(\$3+\$5)+\$300

revenue ...

30p ,where p is the price charged

break even point is where cost = revenue ... now what?

Solving the original question, "what is the break-even price?", is easy, especially given skeeter's post. But I have no idea what "contribution margin" and "contribution rate" mean! Those are not standard "mathematics terms" and should be defined in the problem.
