Lisa wants to take her wireless ear buds and her video game player on a road trip with her roomates. An hour before they plan to leave, she realizes that she forgot to charge them last night. At that point, she plugged in both devices so they can charge for as long as possible before they leave. Lisa knows that her wireless ear buds have 48% of their charge left and that they charge by an additional 10 percentage points every 16 minutes. Her video game player in new, so Lisa doesnt know how fast it is charging but she recorded the battery charge for the first 30 minutes after she plugged it in.
A. What is an equation to represent the percent charge of the wireless ear buds as a function of time in minutes, where t=0 corresponds to the time that she plugged in the devices. What is the slope and what does it mean?
B. What is an equation that represents the percent charge of the video game battery charge as a function of time in minutes, where t=0 corresponds to the time that she plugged in the devices. What is the x-intercept and what does it mean in this context?
C. what is an appropriate domain for these functions? Why?
D. how much time does Lisa need so that both devices are fully charged? Explain
