Colin buys a car for £45500. It decreases in price 6% per year. How much will it be worth in 3 years?
just olya [345]

Answer:

The answer is 33,710 euros.

Step-by-step explanation:

Start by multiplying 45,550 by 6%. This will give 2,730. over the next three years the price decreases, so multiply 2,730 by 3, which is 8,190. Finally, subtract 45,550 by 8,190 to get 33,710.

Help! This is so confusing please
Rus_ich [418]

Given equation is f(x)=6^x

Now it says to find f(2)

that simply means plug x=2 because we see that 2 is written in place of x in f(x) and f(2)

f(2)=6^2

f(2)=6*6

f(2)=36

Hence final answer is f(2)=36
