Answer:
Given, Work cost=£8500
VAT=20%
So VAT= 20% of £8500
20% of 8500 is the VAT
So, Vat= 20/100*8500
= 20/1*85
= 20*85
= 1700
So the VAT to be added on the work cost is £1700
<em>Total cost= Work Cost + VAT</em>
<em>Total cost= £8500+£1700</em>
<em> = £10200</em>
The probability is 8 out of 20 or 40 percent

Answer:
Ralph's current age is 18.
Step-by-step explanation:
Let r and s represent the current ages of Ralph and Sara respectively. Our task here is to determine r, Ralph's age now.
If Ralph is 3 times as old as Sara now, then r = 3s.
Six years from now, Ralph's age will be r + 6 and Sara's will be s + 6. Ralph will be only twice as old as Sara will be then. This can be represented algebraically as
r + 6 = 2(s + 6).
We now have the following system of linear equations to solve:
r + 6 = 2s + 12, or r - 2s = 6, and r = 3s (found earlier, see above).
r - 2s = 6
r = 3s
Substituting 3s for r in r - 2s = 6, we get 3s = 2s + 6, or s = 6. Sara is 6 years old now, meaning that Ralph is 3(6 years), or 18 years old.
Ralph's current age is 18.
