Carmella sells homemade pies for $10 a pie. it costs $2 for the ingredients to bake each pie. carmella bought a new oven for $600. how many pies must carmella bake and sell before she recovers the cost of the oven?

I think what you would have to do is 12 divided by 600 that would equal 50 so im pretty sure she would have to bake and sell 50 pies to recover the cost of the oven

the steps i did were 
1. i added 10 and 2 to get 12
2. i divided 12 into 600 
3. then i got the answer 50

so that's how i found out the total of pies she needed to sell i hope this worked for you.
