Final answer:
Sara's total pay for the week is $451.25, calculated by multiplying her regular rate by the number of regular hours worked, multiplying her overtime rate by the number of overtime hours worked, and summing the two amounts.
Step-by-step explanation:
To calculate Sara's total pay for the week, we need to determine her regular hours and overtime hours. Since she worked 45 hours, the regular hours would be 40 hours and the overtime hours would be 5 hours.
Her regular pay would be calculated by multiplying her regular rate of $9.50 per hour by the number of regular hours she worked (40 hours). So, her regular pay would be $9.50 * 40 = $380.
Her overtime pay would be calculated by multiplying her overtime rate (time and a half) by the number of overtime hours (5 hours) and adding it to her regular pay. So, her overtime pay would be ($9.50 * 1.5) * 5 = $71.25.
Therefore, her total pay for the week would be the sum of her regular pay and overtime pay, which is $380 + $71.25 = $451.25.
