Math Applied to Real World

We explore salary-based calculations, overtime, commissions, and investment scenarios using practical examples. Question 1: Gross Pay Calculation James earns an annual salary of $21,600. He is paid biweekly and works 40 hours per week. To determine his gross pay per pay period, we calculate the number of biweekly pay periods in a year: 52 weeks ÷ 2 = 26 pay periods. Therefore, his gross pay per pay period is $21,600 ÷ 26 = $831 (rounded to the nearest dollar). Question 2: Hourly Rate Calculation James works 40 hours per week. To calculate his hourly rate, we first determine the total hours worked in a year: 40 hours/week × 52 weeks = 2,080 hours. His hourly rate is $21,600 ÷ 2,080 = $10.38/hour . Question 3: Overtime Calculation James’s gross pay for one pay period is $1,180. His regular pay is $831, so the difference represents his overtime pay: $1,180 - $831 = $349. Since overtime is paid at double his hourly rate, his overtime hourly rate is $10.38 × 2 = $20.76. To find out how man...
