12. Julle is looking through a catalogue for ice-cream. She can buy 2 L of triple-chocolate ice cream for $6.30 while the vanilla fudge ice-cream is usually $5.40 for 1.2 L.
What saving does there need to be on the price of the 1.2 L container of vanilla fudge
ice cream for it to be of equal value to the 2 L triple-chocolate container?

Step-by-step explanation:

Julle is looking through a catalogue for ice-cream. She can buy 2 L of triple-chocolate

ice cream for $6.30 while the vanilla fudge ice-cream is usually $5.40 for 1.2 L.

What saving does there need to be on the price of the 1.2 L container of vanilla fudge

ice cream for it to be of equal value to the 2 L triple-chocolate container?

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.
