Savannah was paid $77 for 11 hours of babysitting and $55.25 for 8 hours. What is the constant of proportionality that describes this relationship?

because he had paid the money for her baby sitting

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
