Answer:
When they made their purchases, Frankie's camera was worth $45 more than Gia's camera.
Step-by-step explanation:
The value of Frankie’s camera is
[tex]f(x)=320(0.85)^x[/tex]
where, x is the number of years after purchase.
The value of Frankie’s camera at the time of purchase is the initial value of the function.
Substitute x=0 in the above function.
[tex]f(0)=320(0.85)^(0)[/tex]
[tex]f(0)=320[/tex]
The value of Frankie’s camera at the time of purchase is $320.
From the given table it is clear that g(x)=275 at x=0. It means the value of Gia’s camera at the time of purchase is $275.
Difference between these two values is
$320 - $275 = $45
When they made their purchases, Frankie's camera was worth $45 more than Gia's camera.
