Step-by-step explanation:
Since we have a vertical major axis, our ellipse is vertical.
The equation of a vertical ellipse is
where
(h,k) is the center
a is the semi major axis,
b is the semi minor axis
First, let plug in our center
Semi means half, so
a is half of 14 which is 7
B is half of 8, which is 4.
First, add up his total.
79.95+2*19.99=<span>119.93
Then multiply by 1.075 (this will add the tax to the amount)
That gives us </span><span>128.92475, which we can simplify to 128.92
He had to pay $128.92
