C) The two quantities are equal.
D) The relationship cannot be determined from the information given.

Let's use the strategy of matching operations

Given:
Quantity A: 5(r + t)
Quantity B: 5r + 5

Expand:
Quantity A: 5r + 5t
Quantity B: 5r + 5

Subtract 5r from both quantities to get:
Quantity A: 5t
Quantity B: 5

Divide both quantities by 5 to get:
Quantity A: t
Quantity B: 1

Since there's no way to tell whether t is less than, equal to, or greater than 1, the correct answer is D
