5.Alma's mobile phone is charged to 80% when she takes the phone off the charger. The phone's charge decreases by 15% every 2 hours. Which graph could be used to show the charge of Alma's phone, C, as a percentage as a function of t hours after Alma takes the phone off the charger?(1 point)
A. A function is graphed on a first quadrant coordinate plane. The horizontal axis labeled Time in hours goes from 0 to 12 in increments of 1. The vertical axis labeled Battery Charge in percent goes from 0 to 100 in increments of 2. A line starts at (0, 80), passes through (2, 50) and (4, 20), and ends at approximately (5.3, 0).
B. A function is graphed on a first quadrant coordinate plane. The horizontal axis labeled Time in hours goes from 0 to 12 in increments of 1. The vertical axis labeled Battery Charge in percent goes from 0 to 100 in increments of 2. A line starts at (0, 20), and passes through (4, 50).
C. A function is graphed on a first quadrant coordinate plane. The horizontal axis labeled Time in hours goes from 0 to 12 in increments of 1. The vertical axis labeled Battery Charge in percent goes from 0 to 100 in increments of 2. A line starts at (0, 80), and passes approximately through (2, 95).
D. A function is graphed on a first quadrant coordinate plane. The horizontal axis labeled Time in hours goes from 0 to 12 in increments of 1. The vertical axis labeled Battery Charge in percent goes from 0 to 100 in increments of 2. A line starts at (0, 80), passes through (4, 50) and (8, 20), and ends at approximately (10.7, 0).
