I mean it would be A and D because I don't know why they are both the same answer. If 10 books were sold yesterday, at LEAST 20 are needed to make the goal.
3+2+1/2+1/7
5+1/2+1/7
5+7/14+2/14
5+9/14
5 9/14

maple syrup = x
corn syrup = 50-x
6x + 0.8(50-x)=2.36*50
6x+40-0.8x=118
5,2x=78
x= 15 gallons of maple syrup
50-15 = 35 gallons of corn syrup
First you would do -30x5 which equals -150 then 2-150 equals -148
