Lowell has a credit card that uses the adjusted balance method. For the first 10 days of one of his 30-day billing cycles, his balance was $1360. He then

made a purchase for $470, so his balance jumped to $1830, and it remained

that amount for the next 10 days. Lowell then made a payment of $740, so

his balance for the last 10 days of the billing cycle was $1090. If his credit

card's APR is 28%, which of these expressions could be used to calculate the

amount Lowell was charged in interest for the billing cycle?

-232

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
