Ratio of the number of widgets sold by company E and D in 2006 is 8 to 2 respectively. In other words, company E sold 4 times as many widgets as company D. Company D sold 1.2 million widgets in 2006. If we multiply 1.2 million by 4, we get 4.8 million or 4,800,000, the amount sold by company E.

what about C can't we do something with C?

beginnersmind · Answer

In general if the ration between two numbers, for example C and E, is 5:8 you it is true that:

$$\frac{C}{E} = \frac{5}{8} $$
You can read off C from the graph and solve for E.

I.e:

$$5E = 8*C = 8*3million = 24 million $$
dividing by 5 gives 4.8 million, the same result.

The way the problem is written you can solve it two ways. You can use the ratio between C and E, or the ratio between D and E.

Using D and E leads to easier calculation, but both give the same result.
