At higher elevations water boils at lower temperatures. The temperature at which water boils is called the boiling point of wate
Irina-Kira [14]

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
