6n + 3 - 3 = 9 - 3

6n = 6

n = 1

Step-by-step explanation:

C(t) = 0.32t + 0.10

Step-by-step explanation:

A cell phone charges at a rate of 16% every thirty minutes. It means 32% battery gets charged in one hour.

Then charging of cell phone in t hours = 0.32t

When cell phone is initially plugged into a charger, cell phone had 10% battery so total charge in t hours will be = (0.32t + 0.10)

Then charging of the cell phone may be defined as C(t) = 0.32t + 0.10

2). Therefore, a linear equation defines the charging of cell phone and slope defines the rate of charging of the battery.
