Answer:

5 1/12

Step-by-step explanation:

take the mileage for each day and make it into a normal fraction, then make them all have the same denominator by multiplying the top and bottom numbers by a number that will make the denominator 12. For day 1, take 2 1/2 and make it 5/2 and multiply it by 6 to get 30/12. then for day two take 1 3/4 and make it into 7/4 and multiply it by 3 to get 21/12. then for day three take 5/6 and multipy it by 2 to get 10/12. Now add them all together; 30/12+21/12+10/12= 61/12. now calculate how many times 12 goes into 61, which is 5 with a remainder of 1/12 so the answer is 5 1/12.

1.08t can be written as (1.081/12)12t to give the approximate equivalent monthly interest rate based on an annual rate of 8%. Us

kobusy [5.1K]

Because t is given in years and 1.08 = 1 + 0.08, the annual percent increase
is 8%.
To find the monthly percent increase that gives an 8% annual increase,
use the fact that
t = $\frac{1}{12} * 12 t$ 
and the properties of exponents to rewrite the
model in a form that reveals the monthly growth rate.

$1.08^{t} 
= 1.08^{(1/12)(12t)} 
= (1.08^{1/12}) ^{12t} 
= 1.0064634^{12t}$

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

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.

Reptile [31]

Answer:

Step-by-step explanation:

If there are 3 classrooms that each have 25 desks and there are a total of 87 students, how many more desks need to be added to a 4th classroom, that was originally empty, so that each of the students has a desk to sit in?

25 * 3 = 75

87 - 75 = 12
