Step 1:I'll solve this step by step using the precise LaTeX formatting guidelines:
Step 2:: Identify the components of the percent problem
- The relationship is: $$A = P \times B
- In a percent problem, we have three key components: * Percent (P) * Amount (A) * Base (B)
Step 3:: Analyze the given information
- Percent (P) = $$90\%$$ = $$0.90
- Base (B) = 70 - We need to find the Amount (A)
Step 4:: Calculate the Amount
- $$A = 63
- Substituting the values: A = 0.90 \times 70
Step 5:: Verify the components
- Base = $$70
- Amount = 63
Step 6:: Check the answer choices
- The correct answer is: Percent = $$90\%$$, Amount = $$63$$, Base = $$70
Final Answer
Option d) Percent = 90\%, Amount = unknown (which is 63), Base = 70.
