65. Wheelchair scale reads 192 lb; chair weighs 43 lb. Resident weight =:
Answer: C
The resident's weight is 149 lb.
To determine the resident's weight, subtract the weight of the wheelchair from the total weight shown on the scale. The calculation is 192 lb (total weight) - 43 lb (weight of the wheelchair) = 149 lb (resident's weight).
A) 235
Option A is incorrect because it suggests a total weight that does not account for the wheelchair's weight. Adding the chair weight of 43 lb to 192 lb does not provide the correct resident weight.
B) 199
Option B is also incorrect as it implies an incorrect calculation. If 43 lb were mistakenly added instead of subtracted, it would yield an inaccurate weight, not aligning with the actual calculation needed for the resident's weight.
C) 149
Option C is the correct answer. This is derived by subtracting the weight of the wheelchair (43 lb) from the total weight registered on the scale (192 lb), resulting in the resident's weight of 149 lb.
D) 129
Option D is incorrect because it underestimates the resident's weight. This value does not result from any reasonable calculation involving the total weight and the weight of the wheelchair, leading to an inaccurate conclusion.
Conclusion
The correct answer is 149 lb, as it accurately reflects the resident's weight after deducting the weight of the wheelchair from the total weight. Options A, B, and D do not provide valid calculations based on the given scenario, thereby confirming that they are incorrect.
