Calculate Don's total overtime pay if his basic hourly rate is K4.75 and he worked 12 hours overtime paid at time and a half.

"Time and a half" means 1.5 times the basic hourly rate.

$$\text{Overtime Rate} = 1.5 \times \text{Basic Hourly Rate}$$ $$\text{Overtime Rate} = 1.5 \times \text{K}4.75$$ $$\text{Overtime Rate} = \text{K}7.125 \text{ per hour}$$

$$\text{Total Overtime Pay} = \text{Overtime Rate} \times \text{Overtime Hours}$$ $$\text{Total Overtime Pay} = \text{K}7.125 \times 12$$ $$\text{Total Overtime Pay} = \text{K}85.50$$ $$\boxed{\text{K}85.50}$$

5. A shopkeeper works a basic week of 35 hours for which he is paid K140.00. Calculate his hourly rate of pay.

$$\text{Hourly Rate} = \frac{\text{Total Weekly Pay}}{\text{Basic Hours}}$$ $$\text{Hourly Rate} = \frac{\text{K}140.00}{35}$$ $$\text{Hourly Rate} = \text{K}4.00 \text{ per hour}$$ $$\boxed{\text{K}4.00 \text{ per hour}}$$

A tailor earns K8 000 per annum. Deductions from her gross annual pay are;

• K1 850 for income tax
• K750 for insurance and K450 for pension fund.

6. Calculate the tailor's total deduction

$$\text{Total Deductions} = \text{Income Tax} + \text{Insurance} + \text{Pension Fund}$$ $$\text{Total Deductions} = \text{K}1850 + \text{K}750 + \text{K}450$$ $$\text{Total Deductions} = \text{K}3050$$ $$\boxed{\text{K}3050}$$

7. What is the tailor's net annual pay?

$$\text{Net Annual Pay} = \text{Gross Annual Pay} - \text{Total Deductions}$$ $$\text{Net Annual Pay} = \text{K}8000 - \text{K}3050$$ $$\text{Net Annual Pay} = \text{K}4950$$ $$\boxed{\text{K}4950}$$
