It's C because you need to find how many points each student earned per grade (freshman & sophomore). Then you multiply it by 30 to find out how many points each student scored in the whole class.

Hope this helps!

Ad libitum [116K]

Answer:

Each friend will get  \frac{1}{18} of whole pan of corn bread

Step-by-step explanation:

As given,

Corn bread left = \frac{1}{3}

Total number of friends = 2

So the left bread will divide into 2 parts

So, each person will get = \frac{1}{2} ( \frac{1}{3} ) = \frac{1}{6} of the left bread

Now,

Left bread = \frac{1}{3} of whole bread

And

Each person get  =  \frac{1}{6} of the left bread

                            = \frac{1}{6} ×\frac{1}{3} of whole bread

                            = \frac{1}{18}of whole bread

∴ we get

Each friend will get  \frac{1}{18} of whole pan of corn bread
