Uncle Bruce is baking chocolate chip cookies. He has 36 ounces of dough (with no chocolate) and 10 ounces of chocolate. How much chocolate is left over if he uses all the dough but only wants the cookies to consist of 20% chocolate?	Choices.
A) 2
B) 4
C) 6
D) 3
E) 1
First, you must find the total weight of the mixture given that 80% of it will be dough.   80%*Total = 36 =&gt; (8/10)Total=36=&gt; Total=360/8 =&gt; Total=45 oz,   From there, you must find 10% of the total 40 oz of the mixture.   20%*Total =&gt; (2/10)(45)= 9 oz choclate used,   Not forgetting that the question asks how much chocolate is left over we must subtract the chocolate used from the initial chocolate. 10-9 = 1 oz chocolate left over.   Answer : 1
