62.5 is the answer to your question
Answer:
%35 of them were in color
Step-by-step explanation:
Since 30 percent of the first 200 sold were in color, 200x30/100 = 60 of them were in color.
Since 20 percent of the next 300 sold were in color, 300x20/100 = 60 of them were in color.
Since 90 percent of the last 100 sold were in color, 100x90/100 = 90 of them were in color.
In total, 60 + 60 + 90 = 210 out of 600 were in color.
The percentage is: = → x = = 35
The explicit formula is D. -4n + 15.

Step-by-step explanation:
X = adult tickets
y= child tickets
x + y = 11
44.95x + 34.95y = 434.45
-44.95x - 44.95y = -494.45
-10y = -60
y = 6 child tickets
x + 6 = 11
x = 5 adult tickets
