Answer:
Best deal: 12 for $6
Worst deal: 3 for $2
29.06% difference
Step-by-step explanation:
2.00/3= 0.67
3.50/6= 0.58
6.00/12= 0.50
13.00/24= 0.54
Best deal: 12 for $6
Worst deal: 3 for $2
% difference: (0.67-0.50)/((0.67-0.50)/2) x 100= 29.06% difference
X^2 + y^2 - 2x + 2y - 1 = 0
(x^2 - 2x) + (y^2 + 2y) - 1 = 0
(x^2 - 2x + 1) + (y^2 + 2y + 1) - 1 - 1 - 1 = 0
(x - 1)^2 + (y + 1)^2 - 3 = 0
(x - 1)^2 + (y + 1)^2 = 3
