Find the rate of change, (y2-y1)/(x2-x1), from the data given...
(2.16-1.26)/(12-7)=0.18
(1.26-0.72)/(7-4)=0.18
Since the rate is constant, this is a linear equation of the form y=mx+b. Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...
c(p)=0.18p (cost with respect to pencils is 0.18 times the number of pencils)
This means that for every 5 kilograms of fruit, you'll get 3 kilograms of sugar.
----------------
Let's divide 8 into 5 parts. 8/5 = 5/5 + 3/5 = 1.0 + 0.6 = 1.6
----------------
1.6 x 3 = 3 + 1.8 = 4.8
-------------------
This means that within 8 kg of fruit you'll find 4.8 kg of sugar.
The answer would be (A) 6
