Question

Jonas wants to make a poster of a drawing he made. the original drawing was 8 inches wide he wants the poster to be 30 inches wide. what zoom button setting will he have to use on the library copier to create a poster of this size ?

Answer 1

Answer:

Times 3.75 zoom button.

Step-by-step explanation:

Jonas drawing is 8 inches wide.

He wants to make a poster which is 30 inches wide.

The library copier will have to zoom the drawing 30 ÷ 8 = 3.75 times to make the poster.

So the zoom factor button is times 3.75 button.

Answer 2

Answer:

The answer is 375

Step-by-step explanation:

Here's one way to solve this problem.

1. Let x represent the copier zoom button setting.

2. Write the ratio of the original percent to the copy percent:

100%/ x%

3. Write the ratio of the original width to the copy width

8in./30in.

4. write the proportion equating the two ratios:

100/x = 8/30

5. Cross multiply:

8x = 30 × 100

8x = 3,000

6. Divide both sides by 8:

x = 375

So Jonas will have to use a copier zoom button setting of 375% to create a poster 30 inches wide.

Hope this helped!
