He sold all general admission tickets
Can prove using simultaneous equations
50x + 60y = $1050
x + y = 21 => y = 21-x
50x + 60(21-x) = 1050
50x + 1260 - 60x = 1050
-10x = 1050 - 1260
-10x = -210
x = -210/-10
x = 21
x + y = 21
21 + y = 21
y=0
Since he sold 21 general admission tickets and no VIP tickets
They help by the number of total dots on the diagram, they told you the answer to 8+6=14
Answer:
3
Step-by-step explanation:
-4c - 2 = 10 - 8c
-4c + 8c = 10 + 2
4c = 12
c = 12/4
c = 3
850 - 699 = 151
151/699 = 0.2160 * 100 = 21.60%
