Amount of money that Sarah e a r n s b a r i e s directly with the number I was working a sale earns $320 for working 40 hours of Terminator c o n s t a n t o p r o p o r t i o n a l i t y
The amount of money that Sarah earns varies directly with the number of hours she works, so there is a constant of proportionality involved.
Let's assume the constant of proportionality is "k".
According to the given information, Sarah earns $320 for working 40 hours.
Using the concept of direct proportionality, we can write the equation:
Amount earned = constant of proportionality * number of hours
$320 = k * 40
Solving for the constant of proportionality "k":
k = $320 / 40
k = $8
Therefore, the constant of proportionality is $8.
Now we can use this constant to find the amount of money Sarah earns for any given number of hours she works.
Amount earned = 8 * number of hours
