Answer:

The mean.

Step-by-step explanation:

I would use the mean as the measure of central tendency.

It is the best representation of the data as the variability isn't high; I'd only use the median if outliers are present because outliers don't affect it.

Because there are no outliers here, the mean is better.

Hopefully I helped :)

bagirrra123 [75]

Answer:

132 people bought balcony tickets and 450 bout ground tickets

Step-by-step explanation:

let x be balcony and y for ground

x+y=582

15x+10y=6480  solve by adding(subtracting)/eliminating process

multiply first equation by 15 to eliminate x:

15x+15y=8730

15x+10y=6480      subtract

15x+15y-15x-10y=8730-6480

5y=2250

y=2250/5=450

x+y=582

x=582-450=132
