5 lb book, arithmetic (chapter 7), question 23

by ClashTheBunny Tue Sep 23, 2014 2:02 am

It seems that this question is improperly worded or maybe the solution is wrong.

The question states that 15 employees donated at least $12 and 9 employees donated at least $19. This would mean, to me, that 9 out of the 15 who donated at least $12 were the people who donated $19. $19 is at least $12 after all.

I looked for errata on the book, but there were no better hits than this forum.

Thanks!

Hey Clash,

You're absolutely right. We do have an errata page on our website, in your student center. We'll get on this for the next edition. Thanks!
