Before you answer, shoo the fly away. Some rounded errors may have occurred.

This comic was going to have a grandfather/grandson thing going on to add a lighter, more humorous touch. But then I realized that it didn't need it. So it's a straight math problem, silly as it is, without the usual silly twist.

For the record, the actual ratio of the width to length of the U.S. Flag should be 1:1.9, not 13:25 as presented in the problem. That just made life a little easier. Sorry, my students' aversion to all things fractional (or decimal-equivalent) may be rubbing off on me.

And I'd like to add that the photo of the fireworks in the background was shot by yours truly. So it's used by permission of the owner (myself) and is NOT in the public domain.

I'd say (3*25+4*(25-10)) / (13*25) = 27/65 \approx 41.5%, amirite?

Cool. Now try to figure out the white space. The size of the stars is left as an exercise to the reader. 8-b
