Hello there!
We can make an equation
x = bat and y = ball
x + y = $1.10
x + $1 = y
y must equal 5 cents
5 cents plus 1 dollar 5 cents = 1.10
Hope I was of assistance!

3x-2 is parallel
-1/3-10 is perpendicular because negative reciprocal is always perpendicular
1/3+1 is neither
Just change 1.5 to a fraction so 6/4 then you know you need 3/4 so divide 3.60 and you get $1.30
represents the probability of the event B, knowing that event A has already occurred. It is called conditional probability.
Conditional probability can heavily change the probability of an event, even if you know its apriori probability. Consider this example.
We're flipping two coins, and we define the following events:
Before flipping the two coins, we know that
In fact, there are four outcomes with the same probability:
But what if we condition the probability of C to events A or B? We have
In fact, there's no way that both coins can land on heads, if the first one landed on tails. On the other hand,
Because now that we know that the first coin landed on heads, there are only two possible outcomes:
