Eudora transferred a balance of $6400 to a new credit card at the beginning
of the year. the card offered an introductory apr of 7.8% for the first 3
months and a standard apr of 26.5% thereafter. if the card compounds
interest monthly, what will eudora's balance be at the end of the year?
(assume that eudora will make no payments or new purchases during the
year, and ignore any possible late payment fees.)

$66,504.50

Step-by-step explanation:

For the first 3 months, the interest is 7.6% per month. So, at the end of these 3 months, the balance is

M = 6400 (1+0.078)³ = 6400 . 1.078³ = 8017.45

For the last 9 months, the interest is 26.5% per month, So, at the end of these 9 months, the balance is

M = 8017.45 (1+0.265)⁹ = 8017.45 (1.265)⁹ = 66504.50

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

it is c, trust i got your back lol
