Answer:
Barbara paid total amount of $339.94 before taxes.
Step-by-step explanation:
As tax amount or percentage is not give, we can assume that the sum of all the items is the total cost Barbara paid.
We will add up all the costs.
Entry fee = $18
And separate fee of $7.50 per week for 16 weeks, total amount is =
Cost of bowling ball = $102
Cost of a bag = $39.95
Cost of glove = $11.00
Cost of a pair of shoes = $48.99.
Adding up all values =
=$339.94
Thus, we can say that Barbara paid a total amount of $339.94 before taxes.

Answer:
The absolute difference is:
If we find the % of change respect the before case we have this:
So then is a big change.
Step-by-step explanation:
The subindex B is for the before case and the subindex A is for the after case
Before case (with 500)
For this case we have the following dataset:
500 200 250 275 300
We can calculate the mean with the following formula:
And the sample deviation with the following formula:
After case (With -500 instead of 500)
For this case we have the following dataset:
-500 200 250 275 300
We can calculate the mean with the following formula:
And the sample deviation with the following formula:
And as we can see we have a significant change between the two values for the two cases.
The absolute difference is:
If we find the % of change respect the before case we have this:
So then is a big change.
