Hi, there.
______
Let me start by defining a binomial.
A binomial is an expression with 2 terms. These could be variables, constants, they could have any exponents, but as long as that expression has 2 terms, it's considered a binomial.
Of the 4 choices provided, which one shows an expression with 2 terms?
Only C.
Hope the answer - and explanation - made sense,
happy studying!!!

Let's call:
f = price of 1 cup of dried fruit
a = price of 1 cup of almonds
In order to build the linear system, you need to consider that the total price of a bag is given by the sum of the price of cups times the number of cups in each bag, therefore:
Solve for a in first equation:
a = (6 - 3f) / 4
Then substitute in the second equation:
41/2 f + 6 · (6 - 3f) / <span>4 = 9
41/2 f + 9 - 9/2 f = 9
16 f = 0
f = 0
Now, substitute this value in the formula found for a:
</span>a = (6 - 3·0) / <span>4
= 3/2 = 1.5
Hence, the cups of dried fruit are free and 1 cup of almond costs 1.5$</span>
f = price of 1 cup of dried fruit
a = price of 1 cup of almonds
