Two teachers took out loans from a bank. Mr. Ramirez took out a 3-year loan for $7,500 and paid 4.8% annual simple
interest.
Mr. Vasquez took out a 5-year loan for $7,500 and paid 4.5% annual simple
interest.
What is the difference between the amounts of interest Mr. Ramirez and Mr. Vazquez paid
for their loans?

the answer would be c

49/6 is going to equal 8 1/6

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.

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
