Answer:
The amount of increase per [tex]\frac{1}{3}[/tex] hour by $1.
Step-by-step explanation:
Julian charges $10 for every [tex]\frac{1}{3}[/tex] hour he walks a dog.
He increases his fee by 10%
Now we have to find 10% of $10
Amount increased = [tex]\frac{10}{100} .10 = 1[/tex]
So the amount increased by $1.
The amount of increase per [tex]\frac{1}{3}[/tex] hour by $1.
