Anna's current number of points = 225 points.
She danced correctly and earned = 75 points.
And when she danced incorrectly she loses = 30 points.
Note: For dancing correctly earned points will be added and for dancing incorrectly loses points will be subtracted from the total points has in starting.
So, we can setup an expression as
Current points + earned points - loses points
Plugging values, we get
225 +75 -30 Required expression.
Adding 225 and 75, we get 300.
Therefore, 225 +75 -30 = 300-30.
Subtracting 30 from 300, we get
300-30=270.
Therefore, Anna's final score is 270 points.
The answer is D but i could be wrong

<h3>What is rounding up in mathematics?</h3>
Rounding up can be described as the process that is been used in the mathematics which is been used in the estimation of a particular number in a context.
It should be noted that in rounding the a number up, it is required to look at the next digit at the right hand of the given figures in a case whereby the digit is less than 5,the digit can be rounded down, but in the case whereby the digit is more that 5 then it can be rounded up .
From the given values, we are given the 990,201 and 159,994 and if this were to rounded up to the nearest 10 thousand then we will start from the right hand sides and round down the values less than 5 and round up the values that is more that 5. and their values will be 990000
and 150000.
