Step1: Calculate monthly salary

Divide annual salary by 12.
$78400\div12=\frac{78400}{12}=\frac{19600}{3}\approx 6533.33$

Step2: Calculate weekly salary

Assume 52 weeks in a year, divide annual salary by 52.
$78400\div52 = 1507.69$

Step1: Find the difference in annual salaries

Subtract the annual salary at Bomar Electronics from the annual salary at Delta Tech.
$68125 - 65090=3035$

Step2: Calculate the difference in weekly salaries

Divide the difference in annual salaries by 52.
$3035\div52=\frac{3035}{52}\approx58.37$

Step1: Calculate annual salary

Since bi - weekly means every two weeks, and there are 26 bi - weekly periods in a year.
Annual salary = $1830\times26 = 47580$

Step2: Calculate semi - monthly salary

There are 24 semi - monthly periods in a year.
$47580\div24 = 1982.5$

Answer:

Monthly salary: $\$6533.33$. Weekly salary: $\$1507.69$
