6. Exponential & Logarithmic Functions

As elevation ($A$`A` meters) increases, atmospheric air pressure ($P$`P` pascals) decreases according to the equation $A=15200\left(5-\log P\right)$`A`=15200(5−`l``o``g``P`).

Trekkers are attempting to reach the $8850$8850 m elevation of Mt Everest’s summit. When they set up camp at night, their barometer shows a reading of $45611$45611 pascals. How many more vertical meters do they need to ascend to reach the summit?
