Find the monthly interest payment in the situation described below the song that the monthly interest rate is 1/12 of the annual interest rate you have a average balance of 1,000.00 on your credit card and it carries a 18% annual interest rate

Your average monthly interest rate is0.18/12 = 0.015. So your average monthly interest is0.015×$850 = $12.75. Then the annual interest payments would be 12×$12.75 = $153

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
