<em>Answer:</em>
<em>2 whole 1/4</em>
<em>Step-by-step explanation:</em>
<em>When forming a perfect square trinomial you need to "complete the square".
</em>
<em>All of the steps to completing the square when solving an equation:
</em>
<em>1. The leading coefficient must be 1. </em>
<em>2. Divide b by 2.
</em>
<em>3. Square (b/2)
</em>
<em>4. Add (b/2)^2 to both sides to keep the polynomial balanced.
</em>
<em>5. You can now write the perfect square trinomial and solve.

Answer: $ 45,444.44
Step-by-step explanation:
Given: Jill budgets 18% of her yearly salary for clothing.
His total clothing bill for the year is $8,180.
Let x= her yearly salary
Then according to the question , we have
18% of x = 8180
Convert 18% into decimal by dividing it by 100 , we get
0.18 x= 8180
Multiply both sides by 100
⇒ 18x = 818000
Divide both sides by 18 , we get
x= 45444.44
Hence, her yearly salary = $ 45,444.44
