Q. f(x)=10(1.25)xThe function models f, the price of a rare trading card in dollars x years after its initial release in 1993 . Based on the model, what is the price of the trading card 20 years after its initial release?Choose 1 answer:(A) $15.63(B) $16.39(C) $93.13(D) $867.36
Identify function and value: Identify the given function and the value to substitute for x.The function given is f(x)=10(1.25)x, and we need to find the price of the trading card 20 years after its initial release, so we will substitute x with 20.
Substitute x with 20: Substitute x with 20 in the function f(x)=10(1.25)x.f(20)=10(1.25)20
Calculate (1.25)20: Calculate the value of (1.25)20.(1.25)20=1.2520 Using a calculator, we find that 1.2520≈86.736
Multiply by 10: Multiply the result from Step 3 by 10 to find the price of the trading card.f(20)=10×86.736f(20)≈867.36
Match with given options: Match the result with the given options.The result from Step 4 is $867.36, which corresponds to option (D).
