Answer:
no solution
Step-by-step explanation:
X/3+2=x/3
Subtract x/3 from each side
X/3-x/3+2=x/3-x/3
2 = 0
This is never true so there is no solution
23. You are expected to be familiar with the relationship
... cost + markup = selling price
a) cost + $23.99 = $119.95
... cost = $119.95 -23.99 = $95.96
b) The markup as a fraction of cost is
... markup/cost = $23.99/$95.96 = 0.25 = 25%
c) cost + markup = selling price . . . . the equation we started with
... cost/cost + markup/cost = (selling price)/cost . . . . divide by cost
... 100% + 25% = (selling price)/cost = 125%
25.
a) See part c) of problem 23. Selling price is 126% of cost.
b) Selling price = $450 × 1.26 = $567
c) Markup = $450 × 0.26 = $117
Answer:
10626 different arrangements
Step-by-step explanation:
As we have a total of 23 students and we want to form groups of 3, where the order of the 3 students matters, we can solve this problem using a permutation of 23 choose 3.
The formula for a permutation of n choose p is:
P(n,p) = n! / (n-p)!
So, using n = 23 and p = 3, we have:
P(23,3) = 23! / (23-3)! = 23! / 20! = 23 * 22 * 21 = 10626
So we have a total of 10626 different arrangements of first, second and third place.
