Store A because with option A, the couch is $400 and loveseat is $200 so to buy both it is $600 but she has the discount of $105 off so it would be $495 with option A. With option B, if she buy the couch for $400 and the loveseat for $170 plus the $20 off, the love seat will be $150. So add $150 to $400 and the price is $550. Option a is a cheaper option by $55

The formula for working out the circumference of a circle is:
Circumference of circle = π x Diameter of circle
This is typically written as C = πd. This tells us that the circumference of the circle is three “and a bit” times as long as the diameter."
