bagel emporium sells a dozen bagels for $5.00. This price is no longer
high enough to create a profit. The owner decides to raise the price. He
does not want to alarm his customers with too large of an increase. He
is considering four different plans.

<span>Plan B: Raise the price by 10 percent each week until the price reaches $8.00. - I'd say this plan is the correct one</span>
It sounds like <em>R</em> is the region (in polar coordinates)
<em>R</em> = {(<em>r</em>, <em>θ</em>) : 2 ≤ <em>r</em> ≤ 3 and 0 ≤ <em>θ</em> ≤ <em>π</em>/2}
Then the integral is

You could pick just about anything 3/8 is not the same thing as 5/7 and neither is 3/4
Something that is equivalent would be something like 10/14 or 20/28
The answer to your question is 5
The answer is B
X = 3 and 1/2= Y
3 + 2(1/2) = 4
3 + 1 = 4
Half of 2 = 1, making B the answer
