a. Which equation can be used to find the number of pounds of peanuts needed to create the mixture?

Choose:
 
8x + 4x = 6.50
40 + 8x = 6.5(10 + x)
 
8x + 4x = 6.50(10)
80 + 4x = 6.5(10 + x)

       b.
How many pounds of peanuts are needed for the mixture?

Choose:
 
4 pounds
6 pounds
10 pounds
12 pounds
