Ruth’s credit card has an apr of 10.91%, and it computes finance charges using the previous balance method on a 30-day billing cycle. during the april billing cycle, she made a $45.17 payment on april 10th and a $88.34 purchase on april 17th. her total at the start of may was $847.64. what was her balance at the beginning of april

Balance at the beginning of April = $796.83

Step-by-step explanation:

Let the balance at the beginning of April be "X"

The monthly interest rate = 0.1091/12

(X-45.17+88.34)*(1+0.1091/12) = 847.64   (Since she pays 45.17 and then takes on additional credit of 88.34)

(X+43.17)*1.009091667 = 847.64

X+43.17 = 847.64/1.009091667 = 840

X = 840-43.17

X = 796.83

Balance at the beginning of April = $796.83

The answer is "$797.22" in EDG

Step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.

answer: 12,000
