Joe uses a credit card to buy $396 of groceries and makes no payments for a year. the credit card charges 29% interest. which proportion tells the amount that needs to be added to $396 to find how much he owes in interest at the end of the year?

Please tell me the bank in which Joe uses because I would love it if the bank only calculated interest once every year.  :-)

But to answer your question, assuming it does then to find interest it would be 

x = 396(.29)

Why on earth they have it written like that is beyond me, but to rewrite the correct answer in the form of your answer choices you it would be

 x/396 = 29/100

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
