The rational roots of the polynomial given in the question are -4/5 and 3/4.
Given-
Given polynomial function is,

The given polynomial function has the four-degree equation in which the greatest power of the variable is four. Suppose one root of <em>x </em>is 1 to solve it further. So one factor is,

Rewrite the given equation,





On the factor above equation, we get.

<em>Answer</em><em>:</em>
<em>$</em><em>2</em><em>0</em><em>.</em><em>5</em><em>5</em>
<em>Explanation</em><em>:</em>
- 1apple pie needs 2/3/4pounds of apple
- 1pound cost $2.49
- 2/3/4 = ?
- 2/3/4 ×2.49
- =$6.85 for one pie
- For 3 pies ,
- =$6.85×3
- = $20.55
