Question

What is the multiplier that corresponds to 12% exponential decay(answer choices in picture)?

Answer 1

Answer:

$0.88^x$

Step-by-step explanation:

Exponential decay formula is given as $a(1 - r)^x$, where,

a is the initial amount

r is the decay rate

x is the time interval

Therefore, the multiplier that corresponds to 12% decay is $(1 - r)^x = (1 - \frac{12}{100})^2 = (1 - 0.12)^x = 0.88^x$
