<em>It would be $46 because when you add the 15% tax to it, the total is $61. </em>
<em>$61-15%=$46. To check $46+15%=61! Hope i helped! :-)</em>
I think it is -5,-4,-1/4, 1.75, 6.2, 9, 18 1/2, 21
Answer is B.
5√3(5+2√6)=
25√3+10√18=
25√3+30√2
Note: I multiplied 10 by 3, because the prime factors of 18 are 3, 3 and 2 so I made a pair from the 3 and multipled and was left with 2.
