To find the mean add all the numbers and dived by the number of numbers. So 15 + 23 + 14 + 17 + 21 = 90 / 5 = 18. The mean is 18.
$2500/2 = 1250. 1250/2 = 625. 625/2 = 312.5. 312.5/2 = 156.25. 156.25/2 = 78.125. 78.125/2 = 39.0625 Add all the end numbers up = 2460.9375. 2460.9375/2 = 1230.46875. 2460.9375 - 1230.46875 = 1230.46875. Therefore, she payed back 1230.46875, meaning she had 1230.46875 left in her account. Hope i helped! :D

Answer:
There are 230 seats in the auditorium
Row 51 contains 203 seats.
Step-by-step explanation:
Equation: y = 3x + 50
3x is the rate at which the seats are and 50 is the the starting point.
y = 3(51) + 50
y = 203
Row 51 contains 203 seats.
y = 3(60) + 50
y = 180 + 50
y = 230
