The candle was 10 inches long when new. Each half hour 3/4 inch of the candle burned away. After 4 hours, how long was the candle?

Respuesta :

first I would find out how many inches are burned away in 1 hour, 1 1/2 inches. then u multiply 3/4 by 4 to get 3. then u subtract the 3 by 10 to get 7 inches. the answer is 7 inches.
