Answer 1

Answer:

Answer: 7.25 dollars per hour.

Step-by-step explanation:

The constant of proportionality is the ratio of two variables , y (dependent variable) to x (independent variable).

Given: Savannah was paid 87 for 12 hours of babysitting and 87for12hoursofbabysittingand65.25 for 9 hours.

Here , Number of hours is independent variable and the amount she gets for babysitting with respect to number of hours is dependent variable.

Therefore, c=\frac{y}{x}=\frac{87}{12}=7.25c=

y

=

12

87

=7.25 dollars per hour

Also, c=\frac{y}{x}=\frac{65.25}{9}=7.25c=

65.25

=7.25 dollars per hour

Hence, the constant of proportionality describes the given relationship = 7.25 dollars per hour plz mark me as brainliast
