Answer:
Option B is correct.
Step-by-step explanation:
A proportional relationship is a relationship between two variables where the ratio between the two variables is always the same.
Divide b/a for each option, the option having same ratio for the complete tables have proportional relationship
a)
9/3 = 3
12/4 = 3
20/5 = 4
b)
25/20 = 5/4
30/24 = 5/4
40/32 = 5/4
c)
12/4 = 3
15/5 = 3
24/6 = 4
d)
4/3 = 4/3
9/6 = 3/2
12/16 = 3/4
So, Option B is correct.
You multiply 75 by 0.8 because that is the percentage of the price you pay after 20% is taken
final answer is $60
