Question 597360
The problem can be solved quickly and easily using the method of alligation.

Let "c" denote canola oil and "s" denote soybean oil

We will find the ratio of canola oil to soybean oil in 1 oz of the mixture and then use that information to find the amounts of canola oil and soybean oil in 5.1 oz of the mixture

2.10-1.40=0.70

2.45-2.10=0.35

Therefore, C/S=0.35/0.70

Thus, for every 1.05 parts of total mixture, there are 0.35 parts of canola oil

If there are 5.1 oz of total mixture, then the amount of canola oil is

C=(0.35/1.05)(5.1)=1.70 oz (Answer)

S=5.1-1.70=3.40 oz (Answer)
