Answer:
210 stamps
Step-by-step explanation:
<u>Given:</u>
- Arthur ⇒ a = 3 k
- Yusuf ⇒ y = 5k
- Bill ⇒ b = 6k
<u>Yusuf gave </u><u>x</u><u> stamps to Arthur, then:</u>
<u>Bill gave Arthur 42 stamps more than Yusuf gave to Arthur, then:</u>
- b = 6k - (x+42)
- a = 3k + x + x + 42
<u>Now all 3 have same amount of stamps:</u>
- 5k -x = 6k - x - 42 = 3k + 2x + 42
<u>From the first part of the equation we get:</u>
- 6k - 5k = 42 + x - x
- k = 42
<u>How many stamps did Yusuf have at first?</u>
- y = 5k
- y =5*42
- y = 210 stamps
Yusuf had 210 stamps at first
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>

---f(x)= 15
To find y intercept, make x equal zero
2(0)-5y=-6
-5y=-8
y is equal to 8/5
To find x intercept, make y equal zero
2x-5(0)=-6
2x=-1
x is equal to -1/2
