Answer:
2400
Step-by-step explanation:
2244 is the final price. it includes the VAT based on the actual sale price. and that is then actually 15% lower than the originally marked price.
so, let's calculate backwards :
2244 = 100% sale price + 10% VAT = 110%
1% = 2244 / 110 = 20.40
100% (actual sale price) = 20.40×100 = 2040
now, because of the 15% discount, these 2040 are only 85% of the originally marked price.
2040 = 85%
1% = 2040 / 85 = 24.00
100% (the original marked price) = 24×100 = 2400
Answer:

Step-by-step explanation:
Answer:
2:5
Step-by-step explanation:
divide / simplify the ratio
If you know the derivative 
of some function 
, you can tell exactly who is, up to an additive, constant term. In fact, knowing , you have
In your case, we have
So, the integral is almost immediate:
So, up to some constant additive term, our function is 
To fix this constant, we know that the function passes through the point (6,10), so we have
And so our function is 
If we want to know when this function equals 6, we simply have to ask 
and solve for x, so we have
