250 represents the one time campaign fee because you only have to pay for it once 100 represents the cost per second
Find how fast she runs 1 km:
18/2 = 9 minutes.
So we know have K = 9t
Subtract 18 from both sides:
K-18 = 9t -18
Rewrite the right side:
K-18 = 9(t-2)
2(x4) = 35 - (7-4x)
+4x
2(x8)= 28
/2 /2
8x = 14
