Final answer:
The best representation of Janice's savings unit rate is (1, 200).
Step-by-step explanation:
The unit rate represents the relationship between two quantities with different units. In this case, we're looking for Janice's savings unit rate. The best representation of the unit rate can be found by examining the options given. In option A, (0,0), the second value is zero. Since Janice's savings cannot be zero, we can eliminate this option. In option B, (1, 200), the first value represents time and the second value represents savings. So, for 1 unit of time, Janice would have 200 units of savings. This represents a unit rate of 200 savings per 1 unit of time. Therefore, option B, (1, 200), is the best representation of Janice's savings unit rate.
