Last month the amount on Jaden's bank account statement went from $200 to $150. What was the percent change? (the change is a 25% decrease. Ignore the top half.)

On this month's bank statement, the final balance was $240.

What percent of change was there this month?

the answer is 99.

the answer is 8/21

hope this

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.

what is the question
