Final answer:
Jamie dropped a quarter from an elevation of 6 feet above ground into a well 5 feet below ground. The expression for the change in elevation is 6 + (-5) = 1 foot.
The quarter traveled a total distance of 11 feet.
Step-by-step explanation:
The question asks for an expression representing the change in elevation of a quarter that Jamie dropped. Jamie dropped the quarter from a height of 6 feet above the ground into a wishing well that has a bottom 5 feet below ground level.
To find the total distance the quarter traveled, we add the distance above the ground to the distance below the ground level.
Therefore, the total travel distance is 6 feet + 5 feet, which equals 11 feet.
The expression representing the change in elevation of the quarter is:
- Distance above ground level: 6 feet
- Distance below ground level: -5 feet
- Total change in elevation: 6 feet + (-5 feet) = 1 foot
The quarter ends up 1 foot above ground level after being dropped since it started at 6 feet and then dropped past the ground level to 5 feet below it.
