Cynthia had a credit card with a 17% APR and a $3,265 balance. She had budgeted to have the credit card paid off in 24 months. B
monitta

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.

Tasha has eight more fish than Oscar, who has twice as many fish as Cecilia. If altogether they have 148 fish, how many fish do
Viefleur [7K]

Answer:

They each have 64

Step-by-step explanation:

let C = number of fish that Cecilia has --- then, O = 2C, where O = number of fish that Oscar has --- and T = O + 8 = 2C + 8, where T = number of fish that Tasha has --- then, C + O + T = C + 2C + (2C + 8) = 148 --- or, 5C + 8 = 148 --- or, 5C = 140 --- or, C = 140/5 = 28 --- and, O = 2C = 2(28) = 56 --- and, T = O + 8 = 56 + 8 = 64
