Rice Production

If a farmer plants 100 rice plants, and each plant produces 5 rice grains, how many rice grains does he get in total?

Wage/Salary of Workers

A rice field worker earns 300 pesos for a day of work. How much does he earn if he works for 5 days?

Demand and Supply of Agricultural Products

If the demand for bananas in a market is 2,000 pieces and they have 1,500 pieces, how many more do they need to meet the demand?        Solve it in rational function

Let's solve each of the three problems one by one.

### 1. **Rice Production**
The problem is asking how many rice grains the farmer will get in total if he plants 100 rice plants, and each plant produces 5 rice grains.

**Solution:**

- Number of rice plants = 100
- Rice grains per plant = 5

To find the total number of rice grains, multiply the number of plants by the number of grains each plant produces:

\[
\text{Total rice grains} = 100 \times 5 = 500
\]

So, the farmer will get **500 rice grains** in total.

### 2. **Wage/Salary of Workers**
The problem is asking how much a rice field worker earns if he works for 5 days, with a daily wage of 300 pesos.

**Solution:**

- Daily wage = 300 pesos
- Number of days worked = 5

To find the total earnings, multiply the daily wage by the number of days worked:

\[
\text{Total earnings} = 300 \times 5 = 1500 \text{ pesos}
\]

So, the worker earns **1,500 pesos** for 5 days of work.

### 3. **Demand and Supply of Agricultural Products (Rational Function)**
The problem is asking how many more bananas are needed to meet the demand, given that the demand is 2,000 pieces, but they have only 1,500 pieces.

**Solution:**

- Demand for bananas = 2,000 pieces
- Supply of bananas = 1,500 pieces

The number of additional bananas needed is:

\[
\text{Additional bananas needed} = \text{Demand} - \text{Supply} = 2000 - 1500 = 500
\]

This can also be expressed as a rational function where:

\[
\text{Additional bananas needed} = \frac{\text{Demand} - \text{Supply}}{1} = \frac{2000 - 1500}{1} = \frac{500}{1}
\]

So, they need **500 more bananas** to meet the demand.

Here are 5 related questions you might find interesting:

1. If the farmer plants 200 rice plants, how many rice grains will he get if each plant produces 4 grains?
2. What would the worker's total earnings be if he worked for 10 days at the same daily wage?
3. How would the farmer's total rice grain production change if the number of plants doubled but the grains per plant halved?
4. If the demand for bananas increases by 500 pieces, how many more bananas would they need to meet the new demand?
5. How does the concept of rational functions apply to more complex agricultural supply and demand problems?

**Tip:** Rational functions can be useful in modeling real-world problems, such as balancing supply and demand in economics, by representing relationships between variables in a fraction form.
