<h3>to find:</h3>
the radius of the cone.
<h3>solution:</h3>




<u>hence</u><u>,</u><u> </u><u>the</u><u> </u><u>radius</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>cone</u><u> </u><u>is</u><u> </u><u>5.05</u><u> </u><u>centimeters</u><u>.</u>
3(n+2) ← algebraic expression
.05 is equal to 5%
So for every dollar the mark up is .05cents
So if you times $81 by .05 this will give you the mark up because each of the 81$ needs .05 added to it.
So $4.05 Is the mark up
And
The cost would be markup and original added together
The remainder of the expression x/(x + 1) is a negative one. Then the correct option is D.
