a. Calculate The total number of pixels in an image is the product of the number of pixels in a row and the number of pixels in a column. Your camera produces an image that has 1280 pixels in a row and 1024 pixels in a column. Find the total number of pixels.

b. A megapixel is 1,000,000 pixels. Find, to the nearest tenth, the number of megapixels in the image in part (a).

c. Let m be the number of megapixels in an image, and let l and w be the length and width in inches of a printed photo. A print is clear if the value of the expressionmlwis 0.017 or greater. Can you make a clear 8 inch by 10 inch print of the image in part (a)? Explain.
