Okay, so we need to find the price of the original shirt and the discounted shirt with the 5% tax.
5% (into a real number) is .05
Multiply 20.98 and 15.48 by .05
20.98*.05= 1.049 I am going to round to 1.05
15.48*.05= 0.774 I am going to round to .75
Now we know the prices of both, so we subtract them by each other.
20.98+1.05= 22.03
15.48+.75= 16.23
22.03-16.23= 5.80
But since we rounded the numbers, I would go with choice D.
Hope this helps!

<span>The answer two this question is C.
You can get this answer by multiplying the two polynomials and then simplifying. See the steps below:
(4x^2 - 5)(x + 3) ---> Now multiply the two parenthesis.
4x^3 - 5x + 12x^2 - 15 ---> Arrange the numbers by decreasing exponents.
4x^3 + 12x^2 - 5x - 15
No simplifying can be done since there are no like terms. </span>
Okay so student 2 is correct
Student one is wrong because
The student didn’t multiply by correctly
And student 3 -5(-2) its +10 not -10
