Question

James is tracking the changes in barometric pressure (measured in inches of mercury – inHg) for his science class. On Monday the pressure was 30.01inHg. The pressure dropped by 0.34 inHg on Tuesday, before climbing 1.32 inHg on Wednesday. What was the barometric pressure reading for Wednesday?

Answer 1

The barometric pressure reading for Wednesday was 31.01inHg. This can be calculated by subtracting 0.34inHg from the pressure reading on Monday (30.01inHg) and then adding 1.32inHg, which results in 31.01inHg.

Answer 2

30.99 inHg.

Explanation:

First, subtract how much the pressure dropped on Tuesday from Monday's reading. 30.01 inHg - 0.34 inHg = 29.67 inHg

Then, add how much the pressure climbed on Wednesday to Tuesday's reading. 29.67 inHg + 1.32 inHg = 30.99 inHg
