Answer:
The boiling point of water is between 84 °C and 88 °C when the elevation is between 3.4 and 4.6 km.
Step-by-step explanation:
You want x such that ...
84 ≤ B(x) ≤ 88
84 ≤ 100 -3.5x ≤ 88 . . . . substitute for B(x)
-16 ≤ -3.5x ≤ -12 . . . . . . . .subtract 100
4.6 ≥ x ≥ 3.4 . . . . . . . . . . .divide by -3.5; this reverses the inequality
Set up a proportion.
pounds / milligrams of medicine
195/279 = 130/x
195x = 279 times 130
195x =36,270
x = 36,270/195
x = 186
A patient weighing 130 pounds needs 186 milligrams of medicine.
