For this case we have that if Hernando ate pizza
we have left:
Those
pizza must be distributed equally among 6 people, then:
So, to each friend corresponds 
of pizza
ANswer:
To each of the 6 friends corresponds of pizza
Subtract the advertising cost and interviewing costs from the total budget to see how much is left:
30,000 - 8,600 - 7,650 = $13,750, this is how much they can spend on commission.
Divide the amount they can spend by the rate:
13,750 / 0.055 = 250,000
The maximum selling price for the house is $250,000
The answer to the question
Answer:
The number of permutations of the group of letters given (J, K, L, M, N, O and P) is 7! = 7 . 6 . 5 . 4 . 3 . 2 . 1 = 5,040.
Step-by-step explanation:
The number of permutations without repetition is the number of possible sequences that can occur if we take the letters one by one and is calculated with the factorial of the total number of letters in the group.
Before starting we have 7 possibilities, one for each letter. Once the first letter is chosen randomly, we will have 6 possibilities, after taking the third letter we will have 5 possibilities, and so on.
In total the total number of possibilities to obtain the 7 letters in a certain order are 7 by 6 by 5 by 4 by 3 by 2 by 1, sayed in other words factorial of 7 (7!). The result of the multiplication gives 5,040.
In short we can get the seven letters in 5,040 different sequences.
