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:
Step-by-step explanation:
Let the 3 numbers be 4x , 5x and 6x
4x + 6x = 5x + 55
10x = 5x + 55 Subtract 5x from both sides.
<u> 5x 5x</u>
5x = 55 Divide by 5
x = 55/5
x = 11
Therefore the numbers are
3*11 = 33
4*11 = 44
5*11 = 55
