The image contains calculations for a business scenario, including "Quantity of extra Units to produce", "Current rate of payment per bottle", and "Current rate of payment per hour". It seems to be a problem related to calculating production and payment rates for a company named Julaba Hel.

$$\text{Extra units} = \text{Expected production} - \text{Current production}$$ $$\text{Extra units} = 800,000 \text{ bottles} - 640,000 \text{ bottles}$$ $$\text{Extra units} = \boxed{160,000 \text{ bottles}}$$

$$\text{Total wages} = \text{No. of workers} \times \text{Monthly wage per worker}$$

$\text{Total wages} = 100 \times \text{GH}\text{\$}800$ $\text{Total wages} = \text{GH}\text{\$}80,000$

$$\text{Rate per bottle} = \frac{\text{Total wages}}{\text{Current production}}$$

$\text{Rate per bottle} = \frac{\text{GH}\text{\$}80,000}{640,000 \text{ bottles}}$ $\text{Rate per bottle} = \boxed{\text{GH}\text{\$}0.125 \text{ per bottle}}$

$$\text{Total hours worked} = \text{No. of workers} \times \text{Hours per day} \times \text{Days per month}$$ $$\text{Total hours worked} = 100 \times 8 \text{ hrs/day} \times 20 \text{ days/month}$$ $$\text{Total hours worked} = 16,000 \text{ hours}$$

$$\text{Rate per hour} = \frac{\text{Total wages}}{\text{Total hours worked}}$$

$\text{Rate per hour} = \frac{\text{GH}\text{\$}80,000}{16,000 \text{ hours}}$ $\text{Rate per hour} = \boxed{\text{GH}\text{\$}5 \text{ per hour}}$
