Savannah was paid $87 for 12 hours of babysitting and $65.25 for 9 hours what is the consonant of proportionality that describes the relationship
To find the constant of proportionality that describes the relationship between the hours worked and the payment received, divide the total payment by the total hours worked.
Total payment = $87 + $65.25 = $152.25
Total hours worked = 12 hours + 9 hours = 21 hours
Constant of proportionality = Total payment / Total hours worked
= $152.25 / 21 hours
The constant of proportionality is approximately $7.25 per hour.
