Step-by-step explanation:
A computer costs 927 plus VAT where VAT is 20%. We need to find the total cost of the computer.
The total cost = original cost + VAT
Total Cost = 927 + 20% * 927
20% converts to decimal by moving the decimal 2 units up, so it is 0.2
= 927 + 0.2*927
Multiply to find value of tax
= 927 + 185.4
Add to find the total cost
Total cost = 1112.4 euros
Answer:
15504 different groups
Step-by-step explanation:
We have a total of 20 people, and we want to know how many groups of 5 people we can make, where the order of the people inside the group doesn't matter, so we can solve this question calculating the combination of 20 choose 5.
The formula for combination is:
C(n, p) = n! / (p! * (n-p)!)
In this case, we have n = 20 and p = 5, so:
C(20, 5) = 20! / (5! * 15!) = 20*19*18*17*16 / (5*4*3*2) = 15504
So we have 15504 different groups.
