Answer:
Part A: x·15=$ Part B: Yes
Step-by-step explanation:
Part A: All you have to do is how many pots(x) and multiply it by $15
Part B: 43x15=645 so they do exceed there goal of 500 by 145 dollars
Answer:
Step-by-step explanation:
Let A and B events. We have defined the probabilities for some events:
Where A' represent the complement for the event A
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
So for this case we can solve for P(A) like this:
And now we can find using the total probability rul given by:
And if we replace the values given we got:
And that would be the final answer.
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
