So, Jerome bought a total of 80 cards (8x10) out of which he gave out 30 cards (3x10) so he has 50 cards left. (80-30)

The value of the discriminant is
12.
Since the discriminant is greater than zero, the equation has
two real solutions.
Each numbered angle equals 37°.
I think the Honda and Dodge have the same ratio. If you do the math, the ratio will come out to (12,1) or 12 for both types of cars.
