Xavier spent $84 on supplies (so this is an expense we will make only once), and then he will spend one more dollar for each canvas. So, his total expense for 
paintings will be
Similarly, he will get 8 dollars for each painting, so he will earn
dollars if he will sell paintings.
In order to break even, earnings and costs must be equal:
Subtract p from both sides:
Divide both sides by 7:
So, he has to sell at least 12 paintings to break even.
She should not spin the spinner any more times, the relative probability is already more than the theoretical probability.
If there is only 1 purple section out of 8, that gives purple a 12.5% chance of being spun.
However, Lara got purple 30 out of 120 times. That is 25%. She is already over.
How many of the sections were purple?
The Venn Diagram that represents the problem is shown below
P(E|F) and P(F|E) are the conditional probability.
P(E|F) is given by P(E∩F) ÷ P(F) = ¹/₂ ÷ ¹/₂ = 1
P(F|E) is given by P(F∩E) ÷ P(E) = ¹/₂ ÷ ¹/₂ = 1
