Respuesta :
428.85 because value= initial value × multiplier^(no of years)
Multiplier=100-0.6
99.4÷100
=0.994
Value= 450 × 0.994^8
=428.847.....

Answer:
274.31 ( approx )
Step-by-step explanation:
Given,
The original price of the microwave, P = 450,
Rate of decreasing per year, r = 6%,
Time, t = 8 years,
So, the value of the microwave after 8 years,
[tex]A=P(1-\frac{r}{100})^t[/tex]
[tex]=450(1-\frac{6}{100})^8[/tex]
[tex]=274.30602[/tex]
[tex]\approx 274.31[/tex]
