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

It is A
Step-by-step explanation:
2x + y = 5
y + 3 = 2x
From equation 2:
y = 2x - 3
Substituting in the first equation:
2x + 2x - 3 = 5.
The area of the ceiling:
A = 14² = 196 ft²
We need plaster to cover 196 ft².
196 : 90 = 2.17778
