Answer:
The cost difference is $4.
Step-by-step explanation:
Consider the provided information.
I am paying $60 a month for my service.
I would like to upgrade to the $80.00 service package because my new employer offers a 20% discount with your company.
If i get 20% of discount that means i need to pay only 80% of the original amount.
80% of 80 can be calculated as:
Therefore, now i need to pay $4 extra for the upgrade service.
Hence, the cost difference is $4.

It depends on how b approaches 0
If b is positive and gets closer to zero, then we say b is approaching 0 from the right, or from the positive side. Let's say a = 1. The equation a/b turns into 1/b. Looking at a table of values, 1/b will steadily increase without bound as positive b values get closer to 0.
On the other side, if b is negative and gets closer to zero, then 1/b will be negative and those negative values will decrease without bound. So 1/b approaches negative infinity if we approach 0 on the left (or negative) side.
The graph of y = 1/x shows this. See the diagram below. Note the vertical asymptote at x = 0. The portion to the right of it has the curve go upward to positive infinity as x approaches 0. The curve to the left goes down to negative infinity as x approaches 0.
