The radius of the Outer circle (with r₂) is 6 and the radius of the inner circle (with r₁) is 2. When objects are similar, they have a proportional relationship. If we take the outer circle and squeeze by one third, we get a radius of 6 x 1/3 = 2. On the other hand, if we start with the inner circle and stretch it by 3, we get a radius of 2 x 3 = 6.
Thus, to make r₂ similar, we use a scale factor of 1/3. The third choice is best.

<u>Answer:</u>
The total amount that Eunice paid is $1027.2
<u>Explanation:
</u>
Given the price of the couch is $1200
She was charged a sales tax of 7% and got a discount of 20% because the store was having a sale
Price after sales tax and discount can be calculated
by the formula =
Solving,
= $1027.2
Therefore, Eunice paid a final price of $1027.2 after tax and discount.
If he rounded 5 to 5, 2 to 2 and 3 to 3 he did not estimate low or high.
