Certainly! Let's work through the problem step-by-step:
1. Understanding the Problem: We are asked to decrease 104 by 30%.
2. Identify the Original Value and the Percentage: The original value is 104, and the percentage decrease is 30%.
3. Calculate the Amount to Decrease: To find out how much 30% of 104 is, you multiply 104 by 0.30 (since 30% is equivalent to 0.30 in decimal form).
[tex]\[
\text{Amount of Decrease} = 104 \times 0.30
\][/tex]
4. Compute the Amount of Decrease:
[tex]\[
104 \times 0.30 = 31.2
\][/tex]
So, the amount of decrease is 31.2.
5. Subtract the Amount of Decrease from the Original Value: To get the new value after a 30% decrease, subtract the decrease amount (31.2) from the original value (104).
[tex]\[
\text{Final Value} = 104 - 31.2
\][/tex]
6. Compute the Final Value:
[tex]\[
104 - 31.2 = 72.8
\][/tex]
So, the final value after decreasing 104 by 30% is 72.8.
To summarize:
- The amount of decrease is 31.2.
- The final value after the decrease is 72.8.
