Answer:
She walked neighbor's dog 4 times.
Step-by-step explanation:
It is given that:
Peri earned $27 for walking the dogs 3 times.
Unit rate = [tex]\frac{27}{3}[/tex]
Unit rate = $9 per dog
Now,
Peri worked at the same rate and earned $36.
Unit rate = [tex]\frac{Total\ earning}{Dogs\ walked}[/tex]
[tex]9 = \frac{36}{d}[/tex]
d= 36/9
d = 4
Therefore,
She walked neighbor's dog 4 times.
