The table below shows the typical hours worked by employees at a company. A salaried employee makes $78,000 per year. Hourly emp

uranmaximum [27]

We will recommend option C which is Salaried pay. Salaried employees make more per week than hourly employees.

<h3>How do you find out the best salary option?</h3>

Given that, Salary per year = $78,000.

Hourly employees get paid $26 per hour, but get $39 per hour for each hour over 40 hours.

The total number of working hours from Sunday to Saturday is 47.

The payment for 47 hours of work per week will be given below.

Salary per week = $40 \times 26 + 7 \times 39$

Salary per week = $1313

We know that there are 52 weeks in one year. So the salary for one year is given below.

Salary per year = $1313\times 52$

Salary per year = $68276

We can see that we calculate the yearly salary with per hour rate, the amount will be lower than the salary per year $78000.

Hence we will recommend option C which is Salaried pay. Salaried employees make more per week than hourly employees.
