Question

You are enlarging a photo on your computer screen. The photo starts at 3 centimeters wide. Each time you enlarge the photo, its width is doubled. You enlarge the photo four times. What is the final width of the photo on your screen?

Answer 1

Let's calculate each enlargement:

`3 * 2 = 6 \\ 6 * 2 = 12 \\ 12 * 2 = 24 \\ 24 * 2 = 48`
After the 4th enlargement, the photo is 48 centimeters wide.
