Question

A 22.5 ounce candle burns at the rate of one ounce every 5 hours. write an equation for the amount of candle left

Answer 1

Answer:

y = 22.5 - 0.2t

Step-by-step explanation:

Given;

total number of candle, n = 22.5 ounce

Rate of candle burn, R = 1 ounce per 5 hours  $= \frac{1 \ ounce}{5 \ hours} = 0.2 \ \frac{ounce}{hour}$

The amount of candle left = total initial value - amount burnt

let the amount let = y

y = 22.5 - 0.2t

where;

t is the time in which the candle is burnt

Thus, the equation for the amount of candle left is given by;

y = 22.5 - 0.2t
