Answer: The tractor will be $1442.55 more worth than the truck 5 years after their model years
.
Step-by-step explanation:
Given : The value of a tractor, in dollars, x years from its models year can be predicted by the function [tex]f(x)=15,000(0.90)^x[/tex] .
The value of a certain truck (in dollars) x years from its model year can be predicted by the exponential function given in the table.
As x= 5 , we have
The value of a tractor , 5 years from its models year : [tex]f(5)=150000(0.90)^5=8857.35[/tex]
From , the table , the value of a certain truck 5 years from its model year g(5)=7414.80
Difference= f(5)-g(5)= 8857.35- 7414.80= 1442.55
Hence, the tractor will be $1442.55 more worth than the truck 5 years after their model years
.
