B) Increase 300 By $1%$.
Understanding the Problem
Increasing a number by a certain percentage involves multiplying the original number by a decimal value representing that percentage. In this case, we want to find 1% of 300 and then add it to the original number.
Calculating 1% of 300
To calculate 1% of 300, we need to convert the percentage to a decimal by dividing by 100. So, 1% is equal to 0.01. Now, we can multiply 300 by 0.01 to find 1% of 300.
# Calculating 1% of 300
original_number = 300
percentage = 0.01
result = original_number * percentage
print(result)
Result
The result of the calculation is 3. This means that 1% of 300 is 3.
Increasing 300 by 1%
Now that we have found 1% of 300, we can add it to the original number to find the result of increasing 300 by 1%.
# Increasing 300 by 1%
original_number = 300
percentage = 0.01
result = original_number + (original_number * percentage)
print(result)
Result
The result of the calculation is 303. This means that increasing 300 by 1% results in 303.
Real-World Applications
Increasing a number by a certain percentage is a common operation in finance, economics, and other fields. For example, if a company's sales increase by 1% from one year to the next, the new sales figure would be 1% more than the previous year's sales.
Example Use Case
Suppose a company's sales were $300,000 last year, and they increased by 1% this year. To find the new sales figure, we can multiply the original sales by 1% (or 0.01) and add the result to the original sales.
# Increasing sales by 1%
original_sales = 300000
percentage = 0.01
result = original_sales + (original_sales * percentage)
print(result)
Result
The result of the calculation is 303000. This means that the company's new sales figure is $303,000.
Conclusion
Increasing a number by a certain percentage involves multiplying the original number by a decimal value representing that percentage. In this case, we found 1% of 300 and added it to the original number to find the result of increasing 300 by 1%. The result is 303, which is 1% more than the original number. This operation has real-world applications in finance, economics, and other fields.
