2% profit
Step-by-step explanation:
x = price
50kg = 50x
30kg => 35x
20kg => 16x
35x + 16x = 51x
51x - 50x = x
50x .............. 100%
x ...................... p%
p = 1×100/50 = 100/50 = 2%

y = 2x
I will show two reasons why this equation is correct.
Let x = 1
y = 2(1)
y = 2

In the table, x = 3 is the second choice.
y = 2(3)
y = 6
The second point in the table is (3,6).
Answer: y = 2x
