Mrs. Fisher worked her 40 regular hours last week, plus 4 overtime hours at the double-time rate. Her gross pay was $576. What w
hjlf

Mrs. Fisher's hourly rate of pay, who worked 40 regular hours and 4 overtime hours at double-time rate with gross pay of $576, is <u>$12</u>.

<h3>What is the hourly rate?</h3>

The hourly rate is the rate of pay that an employee is paid daily, weekly, etc.

Usually, overtime hours attract more than the regular hourly rate.

The gross pay is known together with the overtime rate, therefore, the regular hourly rate can be determined as below.

<h3>Data and Calculations:</h3>

Number of regular hours worked = 40 hours

Hourly rate = R

Number of overtime hours worked = 4 hours

Overtime rate = 2R

Total hours worked = 44 hours (40 + 4)

Gross pay last year = $576

$576 = 40R + 4 x2R

$576 = 40R + 8R

$576 = 48R

$12 ($576/48) = R

Thus, Mrs. Fisher's hourly rate of pay, who worked 40 regular hours and 4 overtime hours at double-time rate with gross pay of $576, is <u>$12</u>.
