You owe $1,240.24 on a credit card with a 13.75% apr. you decide to pay $250.00/month toward paying off the credit card. how much is the difference in the interest paid if you pay at the beginning of the month compared to paying at the end of the month?

If you pay at the beginning of the month, the balance on which interest is charged is $250 less than it would be if you paid at the end of the month. The difference is 1 month's interest on $250.

... I = P·r·t

... I = $250·0.1375·1/12

... I = $2.86

The difference in interest paid is $2.86 if you pay at the beginning of the month instead of the end.

what is the model?

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
