<h3>
Answer: 9 months</h3>
================================================
Work Shown:
100 + 22x = 298
22x = 298-100 ........ subtracting 100 from both sides
22x = 198
x = 198/22 .............. dividing both sides by 22
x = 9
It will take 9 months for her to pay off the sofa.
She pays the original $100, and then on top of that, she pays an extra 22*x = 22*9 = 198 dollars since she paid $22 per month for 9 months. So this leads to 100+198 = 298 dollars total to help confirm our answer.

Answer: A.</h2>
Step-by-step explanation:
<em>Victoria's recipe:</em>
<em />
<em>170g of butter = 250 g of flour</em>
<em />
<em>1 g of butter = 250 ÷ 170 = 25/17 g of flour</em>
<em />
<em />
<em>Daughter's recipe:</em>
<em />
<em>340 g of butter = 400 g of flour</em>
<em />
<em>1 g of butter = 400 ÷ 340 = 20/17 of flour</em>
<em />
<em />
<em>Compare:</em>
<em />
<em>20/17 < 25/17 </em>
<em />
<em>⇒ Daughter uses less flour in her cookies</em>
<em />
<em>⇒ the cookies are more dense</em>
<em>So therefor, the correct answer is A. They have too much butter :) </em>
<em>* </em><em>Hopefully this helps:) Mark me the brainliest:)!!!!</em>
