Final answer:
Penny Yoder worked 35 hours this week at the bank, calculated by dividing her gross pay of $306.25 by her hourly rate of $8.75.
Step-by-step explanation:
To calculate the number of hours Penny Yoder worked, we divide her gross pay by her hourly pay rate. Let's denote the number of hours she worked as H.
The formula for gross pay is:
Gross Pay = Hourly Rate × Number of Hours Worked
According to the question:
$306.25 = $8.75 × H
To find H, we divide both sides by $8.75:
H = $306.25 / $8.75
H = 35
Therefore, Penny Yoder worked 35 hours this week at the bank.
