Answer:
a. $121.07
b. $60.9
C. $20.03
Step-by-step explanation:
From the equation given
Y=181.7-20.21x
Where y is in dollars and X is in years
a. To find the resale price after 3years we have, we substitute x=3 into the given equation.
We have
y=181.7-20.21(3)
y=181.7-60.63
y=121.07
The resale price after 3years is $121.07
b. To find the resale price after 6years we have, we substitute x=6 into the given equation.
We have
y=181.7-20.21(6)
y=181.7-120.72
y=60.98
The resale price after 3years is $60.98
C. To find the average decrease per year, we have
[(x=3)-(x=6)]/3
=(121.07-60.98)/3
$20.03
Hence the average annual decrease is $20.03
N is the variable, you solve by subtracting 6 from 20, getting n = 14.
