Final answer:
The correct expression for 'p decreased by 75' is 'P - 75' which means we subtract 75 from the original value of p to find the decreased amount.
Step-by-step explanation:
The question you're asking about, 'Which means "p decreased by 75"?', pertains to the interpretation of algebraic expressions. In this case, the correct expression for p decreased by 75 is C. P - 75. This is because when we say something is decreased by a certain number, we subtract that number from the original amount. To further explain, let's envision p as any number you choose. If we have p as the starting point and we want to decrease this value by 75, we perform the operation p - 75. For example, if p is 100, then 100 - 75 equals 25, meaning p has been decreased by 75 to arrive at 25.
Example Calculation:
- Let p = 100 (assuming p is 100 for this example).
- To decrease p by 75, we calculate 100 - 75.
- The result of this calculation is 25, which is p decreased by 75.
