Answer 1

Answer:

The answer is E

Step-by-step explanation:

We first are going to look at our first term on the table(the number that comes up first) which is $75.

Then we have to find the common factor. So, you divide the second number by the first number( 88.50 divided by 75 which gets us 1.18).

Now, since we found the first term and the common factor, we are going to have to find the exponent for our f(x) equation.  

We know that she bought the painting in 2009! Now the problem is asking how much the painting will cost in 2030. So, you will subtract 2030-2009 which gets you 21! So 21 is your exponent!

Equation:   F(x)= 75(1.18) ^21

The answer that you get is:    $2424.28

Let me know if you have any questions!
