Algebra.Com's Answer #269950 by kingme18(98)![]() ![]() You can put this solution on YOUR website! Your answer is the number of students who owned cats. You forgot about the students who don't own any pets. There are 8 + 15 + 5 = 28 students with pets, so there are 30 - 28 = 2 without pets. Thus, the number without dogs is 8 + 2 = 10. \n" ); document.write( " |
