Total number of seats = 5
Total number of friends = 5
We want to find in how many ways the 5 friends can sit or be arranged in 5 seats. This can be found using permutations.So we are to find the permutations of 5 objects taken 5 at a time. This can be expressed as 5P5.
5P5 = 120
So, the 5 friends can sit in 120 different ways.
The correct answer is option D
Answer: $11,727.27
Step-by-step explanation:
CD: $X
Savings: $4X
Mutual: $(15,000-5X)
0.02X + 0.01*4X + 0.1(15000-5x) = 210
0.06X + 1500 - 0.5X = 210
-0.44X = 210-1500 = -1290
X = 2931.82
4X = 4*2931.82 = $11,727.27
