Stephen runs a pet salon. he is currently grooming 120 dogs per week. if instead of grooming 120 ​dogs, he grooms 121 dogs, he will add ​$68.24 to his costs and ​$66.78 to his revenues. what will be the effect on his profits of grooming 121 dogs instead of 120 ​dogs? ​stephen's profits will change by ​$ nothing. ​(enter your response rounded to two decimal​ places.)

Respuesta :

Profits will change by -$1.46. Just remember that profit = price - overhead. His price is $66.78 and his overhead is $68.24. So for the 121st dog we have: $66.78 - $68.24 = -$1.46 So if Stephen decides to groom that 121st dog, he's going to be losing $1.46 and therefore his profits will be $1.46 lower.
