Divide $13.80 by 4, then multiply by 6 to get $20.70
<em>Let the number is n</em>
<em>it means that n÷2 = -12</em>
<em>multiplying both sides by 2, we get</em>
<em>n = -24 solution.</em>
F(x) = x4(x2 - 1)
f(-x) = (-x)4((-x)2 - 1)
f(-x) = x4(x2 - 1)
from above explanation it is clear that the function is even.
If there are 3 strikes per 10, there should be 9 strikes per 30.
So there are 30 chips in the bag.
