Question

mrs. romero uses a motorized scooter with a battery. the graph shows the percent of life remaining on a fully charged battery as the scooter is used.
which statement describes the meaning of the point (25, 40) on the graph?
motorized scooter battery life

1. the scooter used 25% of the battery life in 40 minutes.
2. the scooter used 40% of the battery life in 25 minutes.
3. the remaining battery life is 40% after 25 minutes of use.
4. the remaining battery life is 25% after 40 minutes of use.

Explanation:

First, identify the axes of the graph: the x-axis represents time used in minutes, and the y-axis represents remaining battery life as a percentage. A point (x, y) on this graph corresponds to x minutes of use and y% remaining battery life. For the point (25, 40), x=25 is the time used, and y=40 is the remaining battery percentage. We then match this to the correct option by eliminating incorrect ones:

• Option 1 swaps x and y values incorrectly.
• Option 1 confuses used vs remaining battery.
• Option 4 swaps x and y values incorrectly.

Answer:

C. The remaining battery life is 40% after 25 minutes of use.
