Profit will increase by $2.3

Explanation:

Data provided in the question:

If instead of grooming 130130 dogs, he grooms 131131 dogs

Marginal cost = $65.82

Marginal revenue = $68.12

Now,

The effect on his profits of grooming 131 dogs instead of 130 dogs will be:

Change in profit = Marginal revenue - Marginal cost

or

Change in profit = $68.12 - $65.82

or

Change in profit = $2.3

Hence,

Profit will increase by $2.3
