Final answer:

The expression (-3 1/2)x8 3/4 represents the context of a discount of 3 1/2 times 8 3/4. This means that an initial value is being reduced by multiplying it by this fraction. Therefore, the context modeled by the expression is Decrease of 3 1/2 times 8 3/4 (C).

Step-by-step explanation:

The expression (-3 1/2)x8 3/4 represents the context of a discount of 3 1/2 times 8 3/4.

This means that an initial value is being reduced by multiplying it by this fraction.

To find the result, we can convert the mixed numbers into improper fractions. (-3 1/2) can be written as -7/2 and 8 3/4 can be written as 35/4. Multiplying -7/2 by 35/4 gives us (-7/2) * (35/4) = -245/8.

So the expression represents a decrease of 245/8.

Therefore, the context modeled by the expression is Decrease of 3 1/2 times 8 3/4 (C).
