Answer:

2(n-9)

Step-by-step explanation:

Hi there!

Let "a number" = n.

"The difference" translates to subtraction, so when the question tells us "the difference of a number and 9", it translates to "n-9".

"Twice" means we'll be doubling something. In this case, we're doubling "n-9":

2(n-9)

I hope this helps!

Answer:

Cynthia will have to pay $152.16 extra in finance charges.

Step-by-step explanation:

Cynthia had a credit card with a 17% APR and a $3,265 balance.

Cynthia’s credit card company has increased her interest rate to 21%.

Here we have two scenarios, 1st when p = 3265 r = 17% and n = 24

Second when p = p = 3265 r = 21% and n = 24

Scenario 1:

$r =17/12/100=0.014166$

EMI formula is :

$\frac{p\times r\times(1+r)^{n}}{(1+r)^{n}-1}$

Putting the values in formula we get;

$\frac{3265\times0.014166\times(1+0.014166)^{24}}{(1+0.014166)^{24}-1}$

= $\frac{3265\times0.014166\times(1.014166)^{24}}{(1.014166)^{24}-1}$

EMI = $161.43

Scenario 2:

r = $21/12/100=0.0175$

Putting the values in formula we get;

$\frac{3265\times0.0175\times(1+0.0175)^{24}}{(1+0.0175)^{24}-1}$

= $\frac{3265\times0.0175\times(1.0175)^{24}}{(1.0175)^{24}-1}$

EMI = $167.77

Now, difference in EMI's = $167.77-161.43=6.34$ dollars

And for 24 months this amount becomes = $24\times6.34=152.16$ dollars

Therefore, Cynthia will have to pay $152.16 extra in finance charges.
