Answer:
[tex] 0.88^x [/tex]
Step-by-step explanation:
Exponential decay formula is given as [tex] a(1 - r)^x [/tex], 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 [tex] (1 - r)^x = (1 - \frac{12}{100})^2 = (1 - 0.12)^x = 0.88^x [/tex]
