Question

Adrean bought a 10 inch candle. After burning it for 2 hours he found it burnt half an inch every hour. Write an inequality to represent how many hours it can burn before it burns out completely.

Answer 1

h(t)= 10-.5t

h is measured in inches, t in hours

in 20 hours it burns out completely

10-.5t = 0

.5t =10

x = 10/.5 = 20
