David and Jillian are playing a board game together. Jillian wants to trade her wool cards for David's ore cards. The double number line shows that David will trade 3 ore cards to Jillian for 6 wool cards. Based on the ratio shown in the double number line, how many wool cards does Jillian need to trade for 4 ore cards?

The answer is 8

Step-by-step explanation:

so first we have to figure out how much wool card cost for 1 ore card. 6 divided by 3 is 2. That means for 1 ore card Jillian needs to give David 2 wool cards so if you multiply 4 times 2 you get 8. The 4 is representing the ore cards and since Jillian is trying to get 4 ore cards she has to add 2 , 4 times. 2+2+2+2 gives you 8 (2 x 4)

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
