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
Proportions have two fractions so the answer is ratios.
Hope it helps :)

Explanation:
Mean- I added all the dots together then divided by 15.
MAD- For the mean I got 6 so I subtracted the difference of each dot from 6, added them all up, and divided them by 15.
