Answer: B. Tabitha figures that the additional benefit of having her own booth ( as opposed to sharing) is at least $300.
Step-by-step explanation:
When Tabitha moved booths, she began to pay $450 per month. The difference between this cost and the cost she was previously paying is:
= 450 - 150
= $300
If Tabitha is paying $300 extra, it must mean that the benefit she is getting from being in her own booth is at least $300 because that would be the only way she would not be making a loss. Were the benefits anything less than $300, she would be making a loss and it would not make any sense for her to continue renting the booth.
