Abby works at the library for 12 hours and makes 108.00 dollars. If p represents her hourly pay, write an equation that will calculate how much Abby made per hour

Direct proportionality formula:

y = kx

where: y varies directly on x by k, the constant of proportionality;

In this problem, we substiture k with p.

y = total earning

p = hourly rate

x = no. of hours worked

y = 108

p = ?

x = 12 hrs

y = px

108 = p (12)

108/12 = p (12) / 12

p = 9 hourly rate or rate per hour.

p = y/x

p = $108 / 12hrs
