Answer:
she will need to trade 8 wool cards for his 4 ore cards
Step-by-step explanation:
basically, the graph shows that three ore cards are equal in value to six wool cards, meaning that ore cards have a value of two wool cards. so if jillian wants 4 ore cards, she will have to give david double the number in wool cards; so 8.
sorry I'm not good at explaining things.
