A newspaper stand sold 1,000 copies of the city newspaper for $1,600 write and solve an equation to find the price of one copy
Vsevolod [243]

Answer: \$1.6

Step-by-step explanation:

Let be "x" the price in dollars of one copy of the city newspaper.

You need to analize the information provided in the exercise:

1. The total number of copies of the city newspaper sold in the newspaper stand is:

Total\ copies=1,000

2. The amount of money earned by selling 1,000 copies of  the city  newspaper is:

Total\ earned=\$1,600

Then, you can determine that the value of "x" can be found with:

x=\frac{Total\ earned}{Total\ copies}

3. Finally, substituting values, you get:

x=\frac{\$1,600}{1,000}\\\\x=\$1.6
