How to Calculate the Number of Additions Nee
Let the initial value be \( A \) (base value), the increment be \( B \) (step size), and the target value be \( C \). To find the number of additions \( n \) needed to meet or exceed \( C \), follow these steps:
Calculation Steps
Set Up the Formula: Start with \( A \) and repeatedly add \( B \) until the result reaches or exceeds \( C \). The condition is:
\( A + n \times B \geq C \)
Solve for \( n \): Rearrange the formula to find \( n \):
\( n = \frac{C - A}{B} \)
Round up \( n \) to the nearest whole number if there's a remainder, ensuring the result meets or exceeds \( C \).
Examples
Example 1: How many times will you add 5 to 65 so that the sum is 80.
Solution:
\( n = \frac{80 - 65}{5} = 3 \)
Result: You need to add 3 times.
Example 2: How many times will you add 5 to 100 so that the sum is 200.
Solution:
\( n = \frac{200 - 100}{5} = 20 \)
Result: You need to add 20 times.
Example 3: How many times will you add 8 to 20 so that the sum is 50.
Solution:
\( n = \frac{50 - 20}{8} = 3……7 \)
Since there's a remainder, round up to ensure the total meets the target:
