Question

julie collects antiques. she bought one antique for $300. its current value is represented by the expression 300(0.75)^t, where t is the number of years julie has owned the antique. is julie’s antique going up or down in value? julie’s antique is going in value.

Explanation:

Step1: Identify decay/growth factor

The expression is $300(0.75)^t$, where the base of the exponent is $0.75$.

Step2: Compare factor to 1

Since $0 < 0.75 < 1$, this is an exponential decay model, meaning the value decreases over time.

Answer:

down
