I think it is a direct variation because if you divide 9/3, 27/3, 39/13, and 60/20 it will all give you the same number which is 3.
I hope this helps.
It should be B If I am correct if I am not I am sorry
Blue 9 x 3 = 27
red 3 x 3 = 9
27 + 9 = 36
I hope this helps
The correct answer is the second choice.
Paolo made an error when he cross multiplied the proportion. He should have multiplied the 3 and the 8 and also the 12 and the x.
The second line should be:
12x = 24
About 1.19 %
80*1.19= 95.2 Since 2 is not 5 or above it get knocks down to 95 exactly
