Joanie takes a  6000 dollar  loan to pay for her car. The annual interest rate on the loan is 12percent . She makes no payments for 4 years, but has to pay back all the money she owes at the end of 4 years. How much more money will she owe if the interest compounds quarterly than if the interest compounds annually? Express your answer as a dollar value to the nearest cent.

-----------------------------------

Compounded annually it will become   6000(1+0.12)^4 = 9441.11 dollars,   which means the interest component is 441.11 dollars

----------------------------------

4 years is 4*4=16 quarters,    and     12% per year (nominal) is   12/4 = 3% per quarter

So 6000 dollars will grow to       6000(1+0.03)^16 = 9628.24 dollars (to the nearest cent)  

so that will be  3628.24 dollars interest

You can finish it :)

I had to get rid of the dollar signs because the program thought it was latex and it didn't print properly.  

This doesn't make much sense.

Perhaps this is part of a larger question?

Actually

-b/(2a)=4

The leading term of f(x) is  x^4

The leading term of g(x) is  2x^4

The leading term of their product will be   2x^8

So what is the degree going to be?

You are welcome Jenny :)

Daniel has been saving part of his allowance in a bag every month. The bag contains 2 dollar notes and 10 dollar notes and had a total value of 2148 dollar. 18 pieces of 10 dollar notes were exchanged for 2 dollar notes of the same value. IN THE END The number of 10 dollar noted was the same as 2 dollar notes. How many 2 dollar notes were there at first?

Let x be the initial number of 2s and y be the initial number of tens.

2x+10y=2148

18 tens is equal to 90 twos.

now if I reduce y by 18 I get y-18

and tht means I will then have  x+90   twos.

I am told these must be the same so     y-18=x+90

I am going to let you figure it out from there.

You are still being careless, and not putting in the time required to even copy the question properly.

You left out important information.

Idyllic, this is mainly for your benefit.   

If a linear equation is of the from       ax+by+c=0      or     ax+by=c

Then the gradient will be      -a/b

This simplifies what you have done enormously.    

How about you edit your question so that it has no latex (coding) in it,

1)  I do not understand the question

2)  What is the address of your original post?
