Question

When Logan left his house this morning, his cell phone was 24% charged and it then started to lose 3% charge for each hour thereafter. Write an equation for B, in terms of t, representing the charge remaining in Logan's battery, as a percentage, t hours after Logan left his house.

Answer 1

Equation: B = 23 - 3(t)

Explanation:

24 is the percent after it was charged, the 3% is the difference, and your time, which is (t). You deduct 3% for each hour. As a result, your equation would be B = 24 - 3(t).

Answer 2

B = 24% - t(3%)

Explanation:

You have you battery at 24% represented by B. you have your 3% which is your difference (d). and your hour which is t. For every hour you are subtracting 3%. So your equation would be B = 24% - t(3%)
