Answer :
Karen's original weight can be calculated using the formula: 86.5 = 0.85 * Original Weight. Her original weight is approximately (b) 101.8 pounds.
Karen's original weight can be calculated by considering that the 86.5 is 85% of her original weight (100% - 15% = 85%).
We use the equation:
86.5 = 0.85 * Original Weight
Solving this:
- Divide both sides by 0.85:
Original Weight = 86.5 / 0.85 - This gives:
Original Weight = 101.76
Rounding to the nearest tenth, we find that her original weight was approximately 101.8 pounds. Therefore, the correct answer is B. 101.8.
Answer:
B. 101.8
Step-by-step explanation:
100% - 15% = 85%
85% = 86.5
100% = 86.5 ÷ 85 x 100
= 101.76 (rounded 101.8)
