Given:

To answer this one, we need variables.

Let:

x = sales for the 1st year

x+3 = sales for the 2nd year

2(x+3) = sales for the 3rd year

Sales for the 3rd year = 38 million $

Asked: Sales for the 1st year in millions of dollars

Mathematical Sentence:

2 (x +3) = 38

x = ?

Solution:

2 (x +3) = 38

2x + 6 = 38

2x = 38 - 6

2x = 32

x = 16

Answer:

The 1st year sales in million dollars that is equal to x is 16 million dollars.

Check:

If 1st year is really 16 million dollars then,

2nd year = 1st year + 3 million dollars = 16 + 3 = 19 million dollars

3rd year = twice 2nd year = 19 x 2 = 38 million dollars, CORRECT

Final answer: 16 million dollars
