When lit, a candle loses 8% of the unlit candle every hour. Janet lit a candle with an original height of 5 inches. Until the candle has been burning for at least ___ hours, the height of her candle will be more than four inches. Please help! This was on a test but it’s confusing to me!

2.5 hours

Step-by-step explanation:

We are given that

Original height of candle=5 in

Every hour candle loses =8% of 5 in=0.4

According to question

Subtract 4 from both sides we get

Divide by 0.4 on both sides

x=2.5 hours

Until the candle has been burning for at least 2.5 hours, the height of her candle will be more than four inches.
