Answer:

6 weeks

Step-by-step explanation:

You can create linear equations to model this.

Science Club:

y = 10x + 20

Math Club:

y = 5x + 50

These can be solved using substitution:

5x + 50 = 10x + 20

-5x -5x

--------------------------

50 = 5x + 20

-20 -20

----------------------------

30 = 5x

/5 /5

------------

6 = X

Plug into one of the original equations:

y = 10x + 20

y = 10(6) + 20

y = 80

The point at which they intersect is: (6, 80)

Since X represents the number of weeks, it would be 6 weeks before they have the same balance.

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:

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