⇒ 
Now, taking log both sides we get,
y log 1.12 = log 3 {Since, 
}
⇒ 0.04922y = 0.477712
⇒ y = 9.694 years (Answer)

Answer:
$195311
Step-by-step explanation:
Given the expression yˆ=20646*0.86x
Given that the number years 11
And x represent the number of years
Substituting x=11 in the expression for the cost we have
yˆ=20646*0.86(11)
yˆ=20646*9.46
yˆ=20646*9.46
yˆ=195311.16
From the analysis he purchased the car fro $195311
