Picture Perfect (RP3A)

You have designed a picture that is shaped as a square. The dimensions of your picture are 6 inches by 6 inches. You want to make it into a poster with dimensions of 13 inches by 13 inches. The duplication machine has three settings:

• one setting that reduces the linear measure by a factor of 75%;
• one that enlarges the linear measure by a factor of 140%;
• and one that just makes identical copies or applies the factor of 100%.

How many multiple enlargements or reductions will you need to make in order to create a poster that has sides 13 inches long (accurate within five-hundredths)? Explain what setting was used and how that changed the measurements of the copy for each step in the process.
