Answer:
The graph that has the points (2,4) and (4,8) should be the answer.
Step-by-step explanation:
This is the answer because if you see the ratio 2:4, that means that for every 2 offense cards there are 4 defense cards. As you continue to go up it would be (4,8), (6,12), (8,16), and so forth.
S = n(a1 + an)/2
2S = n(a1 + an)
2S = na1 + nan
nan = 2S - na1
an = (2S - n a1)/n
Multiply the cost per mile by number of miles “m” and add that amount to the $50:
