Is the file you just attached what your teacher said needed to be corrected?

highschoolmom2010 · Answer

yes.....

anonymous · Answer

hmm...give me a minute to look it over

anonymous · Answer

Wait, were you not supposed to round the final answer?

highschoolmom2010 · Answer

it says to round it.....

anonymous · Answer

Sorry about that. My internet is acting screwy.
Also, I've checked back over your work and found that on the second line you have already solved for 11(1.25) and put 13.75, so you don't need to write 11(1.25) again.
Does that make sense?

anonymous · Answer

Eh, don't feel to bad. I'm notorious for making them. ^_^
