The answer your looking for is 46
Answer:
Step-by-step explanation:
The question is slightly ambiguous. The problem is, do you find the first 40 hours using 10x and then the second equation using x >40. I don't think so, but it should be made clear. It turns out that the first 40 hours does equal 400 so that you can use the second expression with no worries.
w(53) = 15(53 - 40) + 400
w(53) = 15(13) + 400
w(53) = 195 + 400
w(53) = 595
Answer:
169 mg
Step-by-step explanation:
The ratio of medicine quantity to body weight is the same for both patients, so ...

Multiply by 156 lb:
amount = (143 mg)(156/132) = 169 mg
The patient requires 169 mg of medicine.
