Brent has a diagram that he needs to place into areport. It is only 3.5” tall x 4" wide, but it needs to be about twice that big to make the impact he wants. Brent has use of a photocopy machine that can enlarge the height and width of an image by 20%.

 

If he repeatedly uses the machine to enlarge each subsequent image, what is the minimum number of times he will have to make a copy to get the image to at least 7" tall?

3.5 * (1.2)x  = 7

1.2x = 2

x = log2/log1.2 = 3.8         ~~ 4 times
