The price of a computer component is decreasing at a rate of 12% per year. State whether this decrease is linear or exponential. If the component costs70 $ today, what will it cost in three years?

In three years, cost (Value) = 47.70

Step-by-step explanation:

When the decrease is relative to the last value, it is exponential.

Depreciations are usually exponential.

In three years,

Value = 70*(1-0.12)^3

= 47.70

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
