Answer :
Final answer:
To determine Ms. Smith's weight, subtract the weight of the wheelchair (23 pounds) from the total measured weight (172 pounds), which gives us 149 pounds as her weight excluding the wheelchair.
Explanation:
To find Ms. Smith's weight excluding the wheelchair, we subtract the weight of the wheelchair from the total weight.
The weight of the wheelchair is given as 23 pounds. The total weight of Ms. Smith and her wheelchair is 172 pounds. We perform a simple subtraction to solve for her weight:
Ms. Smith's weight = Total weight - Wheelchair's weight = 172 pounds - 23 pounds = 149 pounds. Therefore, the correct answer is 149 pounds.
