Harper just lit a new candle and then let it burn all the way down to nothing. The length of the candle remaining unburned, in inches, can be modeled by the equation L
=
15
−
1.5
t
,
L=15−1.5t, where
t
t represents the number of hours since the candle was lit. What is the slope of the equation and what is its interpretation in the context of the problem?

let x be the money she spent so that she can earn the free t-shirt.
