Amanufacturer produces microwaves. she estimates that by selling them for x dollars each, she will be able to sell 230-3x each week.
determine what price will yield a maximum revenue. ( round your answer to two decimal places.)

7 is the median   7.875 is the mean

step-by-step explanation:

3,4,5,6,8,11,13,13

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.
