1 answer:
Answer:
y = 22.5 - 0.2t
Step-by-step explanation:
The given information includes;
total weight of the candle, n = 22.5 ounces
Candle burn rate, R = 1 ounce every 5 hours
The remaining candle amount is calculated as initial amount minus burnt amount
Let the remaining amount be y
y = 22.5 - 0.2t
where;
t represents the time the candle has been burning
Therefore, the equation for the leftover candle is expressed as;
y = 22.5 - 0.2t
