Final answer:
Based on the information provided, there are only eight cards available, making Brianna's claim correct that only eight cards can be used, as the ninth card does not exist.
Step-by-step explanation:
Arturo claims that it's possible to use all nine cards here. Brianna says the most you can use is eight. To determine who is correct, let's consider the information given. We have eight cards, five green and three yellow. Since we only have eight cards in total, Brianna is correct. The most we can use is eight cards, not nine.
Regarding the assertion made by Arturo that it's possible to use all nine cards here, compared to Brianna's claim that the most cards one can use is eight, there seems to be a discrepancy related to the number of cards available. The information provided mentions only eight cards - five green and three yellow. If there are indeed only eight cards to begin with, then Arturo claims would be incorrect, and Brianna's claim would be accurate as you cannot use more cards than what is available. Since the total number of cards is eight, it is impossible to use all nine cards because the ninth card does not exist.
