Nostrana [21]

Answer:

B(75) represents the percent of battery full after 75 minutes of game play

Step-by-step explanation:

Let m represent the number of minutes of game play. If 1% of the battery is drained every five minutes of game play, then after m minutes of game play $\dfrac{m}{5}\%$ was drained.

The battery starts off at 80% full. After m minutes the battery will have

$B(m)=80-\dfrac{m}{5}$

percent full.

When $m=75$ minutes, then

$B(75)=80-\dfrac{75}{5}=80-15=65\%.$
