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


notice, if the original area was πr², then the new area has a factor in front of it, that much.
Answer:
25 rides
Step-by-step explanation:
has $28.50
15.75 + 0.50r
28.50
Subtract 15.75
0.50r
12.75
r
25.5
you can't have half rides, so 25 rides
