Answer:

the simple interest is <em>36.</em>

Step-by-step explanation:

To find the answer we will first<em> divide 3 by 100</em> and we get <em>0.03.</em>  Now <em>multiply 0.03 by $200</em>, which is<em> 6</em>.  Then <em>multiply 6 by 6</em> <em>months</em> and we get 36.  Therefore, <em>36 is our answer. </em>

At Elisa's printing company, there are two kinds of printing presses: Model A, which can print 70 books/ day, and model B, which
Dmitrij [34]

Answer:

9 Model As.

Step-by-step explanation:

Let A represent Press A and let B represent Press B.

So, they own 14 total presses. This means that:

A+B=14

They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:

70A+55B=905

This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:

A=14-B

Substitute this into the second equation: "

70(14-B)+55B=905

First, we can divide everything by 5 to simplify things:

14(14-B)+11B=181

Distribute the left:

196-14B+11B=181

Combine like terms:

-3B+196=181

Subtract 196 from both sides:

-3B=-15

Divide both sides by -3

B=5

So, the company has 5 Model B presses.

Which means that the company has 14-5 or 9 Model A presses.

And we're done!
