Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![### Writing and Evaluating a Function That Models a Real-World Scenario
An amusement park charges an admission fee of 50 dollars for each person.
Let \( C \) be the cost (in dollars) of admission for \( P \) people.
**Task:**
1. Write an equation relating \( C \) to \( P \).
2. Use this equation to find the cost of admission for 11 people.
**Solution:**
- **Equation:**
\[ C = 50P \]
- **Cost for 11 people:**
\[ C = 50 \times 11 = 550 \, \text{dollars} \]
**Tools:**
- A box to input the equation.
- Options to check and reset the input.
**Graphical Elements:**
- Buttons with symbols such as squares and a multiplication sign, typically used for formatting or entering equations.
