Step-by-step Solution for Part-a:
<u>We know that:</u>
- Row-1: 20 seats
- Row-2: 20 + 11
- Row-x: 20 + (11x - 11)
Since the number of rows in rows x is 20 + (11x - 11), the formula to calculate the number of seats in each row is 20 + (11x - 11).
<h3>________________________________________________</h3>
Step-by-step Solution for Part-b:
<u>We know that:</u>
- y rows = 174 seats
- Obtained rule from part-a: 20 + (11y - 11)
<u>Solution:</u>
- 20 + (11y - 11) = 174 rows
- => 20 + 11y - 11 = 174 rows
- => 9 + 11y = 174 rows
- => 11y = 174 - 9 rows
- => 11y = 165
- => y = 165/11
- => y = 15
Hence, the row which has 174 seats is row 15.

There would be only 1 pint left of iced tea in the pitcher.
So, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4. So she's 75% of the time effective.
Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.
Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.
so, which fraction is highest 3/4, or 2/3 or 2/3? neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.
so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.

notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.
