Final answer:
Jaqulin ended her day at 14,169 feet on Mt. Everest after climbing up 15,543 feet and then descending to retrieve her axe that fell 1,374 feet.
Step-by-step explanation:
Jaqulin climbed up Mt. Everest 15,543 feet before dropping her ice axe, which then fell 1,374 feet. To determine Jaqulin's location on Mt. Everest at the end of the day after retrieving her axe, we subtract the distance the axe fell from her initial height climbed:
Initial height climbed = 15,543 feet
Distance axe fell = 1,374 feet
Jaqulin's location at the end of the day (in feet) = Initial height - Distance axe fell
Jaqulin's location at the end of the day (in feet) = 15,543 feet - 1,374 feet
Jaqulin's location at the end of the day (in feet) = 14,169 feet.
Thus, at the end of the day, Jaqulin is at 14,169 feet on Mt. Everest.
